EMERGENCY AIRWORTHINESS DIRECTIVE

U.S. Department
Aircraft Certification Service of Transportation
Washington, DC Federal Aviation
Administration

We post Emergency ADs on the internet at www.faa.gov/aircraft/safety/alerts.

DATE: March 12, 2008
AD #: 2008-06-51

This emergency airworthiness directive (AD) 2008-06-51 is sent to all owners and operators
of Lycoming Engines IO, (L)IO, TIO, (L)TIO, AEIO, AIO, IGO, IVO, and HIO series reciprocating
engines, Teledyne Continental Motors (TCM) TSIO-360-RB reciprocating engines, and Superior Air
Parts, Inc. IO-360 series reciprocating engines with certain Precision Airmotive LLC RSA-5 and
RSA-10 series fuel injection servos.

Background

This emergency AD results from eighteen reports of fuel injection servo plugs, part number
(P/N) 383493, that had loosened or completely backed out of the threaded plug hole on the regulator
cover of the fuel injection servo. These servo plugs were installed with servo plug gasket, P/N
365533, under the plug hex-head. Precision Airmotive LLC investigated and determined that servo
plug gasket, P/N 365533, can shrink from engine heat, causing the plug to lose torque against the
servo regulator cover, allowing the plug to vibrate out. The threads on the plugs were also found
damaged. Servo plug gaskets, P/N 365533, installed on RSA-5 and RSA-10 series fuel injection
servos since August 22, 2006, are made of a different material than the previous gasket part number
used. This condition, if not corrected, could result in a substantial loss of engine power and
subsequent loss of control of the airplane.

Explanation of Relevant Service Information

We have reviewed Precision Airmotive LLC Mandatory Service Bulletin (MSB) No. PRS107, Revision 1, dated March 6, 2008. The MSB describes procedures for inspecting servo plugs for
looseness and damage, inspecting the servo regulator cover threads for damage, on fuel injection
servos that have a servo plug gasket, P/N 365533, installed, inspecting the gasket for damage,
reinstalling acceptable parts, and torquing the servo plug to a new, higher torque to help maintain the
proper clamp-up force against the plug and cover.

Interim Action

These actions are interim actions and we might take additional rulemaking actions in the
future.

FAA’s Determination and Requirements of the Rule

We have identified an unsafe condition that is likely to exist or develop on other RSA-5 and
RSA-10 series fuel injection servos of this same type design. This AD requires inspecting servo plugs
for looseness and damage on fuel injection servos that have a servo plug gasket, P/N 365533, installed, inspecting the servo regulator cover threads for damage, inspecting the gasket for damage,
reinstalling acceptable parts, and torquing the servo plug to a new, higher torque to help maintain the
proper clamp-up force against the plug and cover.

Interim Action

The actions required by this AD must be done by an FAA-licensed mechanic.

Authority for this Rulemaking

Title 49 of the United States Code specifies the FAA’s authority to issue rules on aviation
safety. Subtitle I, Section 106, describes the authority of the FAA Administrator. Subtitle VII,
Aviation Programs, describes in more detail the scope of the Agency’s authority.

We are issuing this rulemaking under the authority described in Subtitle VII, Part A,
Subpart III, Section 44701, “General requirements.” Under that section, Congress charges the FAA
with promoting safe flight of civil aircraft in air commerce by prescribing regulations for practices,
methods, and procedures the Administrator finds necessary for safety in air commerce. This
regulation is within the scope of that authority because it addresses an unsafe condition that is likely
to exist or develop on products identified in this rulemaking action.

Determination of Rule’s Effective Date

We are issuing this AD under 49 U.S.C. Section 44701 according to the authority delegated to
me by the Administrator, and it is effective immediately upon receipt.

2008-06-51 Precision Airmotive LLC: Docket No. 2008-NE-10-AD.

Effective Date

(a) Emergency AD 2008-06-51, issued on March 12, 2008, is effective upon receipt.
Affected ADs

(b) None.
Applicability

(c) This AD applies to the following reciprocating engines with an installed Precision
Airmotive LLC, RSA-5 or RSA-10 series fuel injection servo, having a servo plug gasket, part
number (P/N) 365533, installed under the fuel injection servo plug, P/N 383493:
(1) Lycoming Engines IO, (L)IO, TIO, (L)TIO, AEIO, AIO, IGO, IVO, and HIO series
reciprocating engines, regardless of displacement, either new, rebuilt, overhauled, or repaired since
August 22, 2006, and/or with an affected fuel injection servo installed either new, rebuilt, overhauled,
or repaired since August 22, 2006.
(2) Teledyne Continental TSIO-360-RB reciprocating engines, either new, rebuilt,
overhauled, or repaired since August 22, 2006, and/or with an affected fuel injection servo installed
either new, rebuilt, overhauled, or repaired since August 22, 2006.
(3) Superior Air Parts, Inc. IO-360 series reciprocating engines, either new, rebuilt,
overhauled, or repaired since August 22, 2006, and/or with an affected fuel injection servo installed
either new, rebuilt, overhauled, or repaired since August 22, 2006.
(4) This AD also applies to any other Precision Airmotive LLC fuel injection servos received
since August 22, 2006, or any fuel injection servos that have had the fuel injection servo plug, P/N
383493, removed during maintenance since August 22, 2006.
Unsafe Condition

(d) This AD results from eighteen reports of fuel injection servo plugs, P/N 383493, that had
loosened or completely backed out of the threaded plug hole on the regulator cover of the fuel
injection servo. We are issuing this AD to prevent a lean running engine, which could result in a
substantial loss of engine power and subsequent loss of control of the airplane.
Compliance

(e) You are responsible for having the actions required by this AD performed before further
flight, unless the actions have already been done. The actions required by this AD must be done by an
FAA-licensed mechanic.

Initial Inspection

(f) Inspect the fuel injection servo plug, P/N 383493, for looseness, by attempting to turn it by
hand, while being careful not to damage the safety wire or seal. If the plug moves, it is loose.
(g) If the plug is not loose, go to paragraph (i) of this AD.
(h) If the plug is loose, do the following:
(1) Carefully cut and remove the safety wire that spans between the servo plug and regulator
cover only.
(2) Remove the servo plug while ensuring that the gasket, P/N 365533, that is behind the plug,
is not lost. The gasket may be slightly stuck to the regulator cover.
(3) Examine the threads on the servo plug and regulator cover for damage. Threads should be
smooth and consistent, with no burrs or chips. The servo plug outer diameter threads should also
measure within 0.7419-0.7500-inch.
(4) If the threads on either the servo plug or the regulator cover are damaged, or do not
measure within the limits in paragraph (h)(3) of this AD, the servo is not eligible for any installation
and must be replaced before further flight.
(5) Inspect the gasket, P/N 365533, for tears and other damage. We are allowing the re-use of
undamaged gaskets. Replace damaged gaskets with a new gasket, P/N 365533.
(6) When reassembling, do not install any servo plug or regulator cover that is not eligible for
installation. Install the gasket onto the servo plug and reassemble the servo plug to the regulator
cover.
(7) Torque the servo plug to a new, higher torque of 90-100 in-lbs, to help maintain the proper
clamp-up force against the plug and cover.
(8) Safety wire the servo plug with 0.025-inch diameter wire to the regulator cover.
Information on properly safety wiring the plug can be found in Precision Airmotive LLC Mandatory
Service Bulletin No. PRS-107, Revision 1, dated March 6, 2008.
(9) Inspect all other safety wire on the servo. Replace any that are damaged.

Repetitive Inspections

(i) At every engine oil change or within every 50 hours of engine run time, whichever occurs
first, repeat the inspection and remedial steps specified in paragraphs (f) through (h)(9) of this AD.
Special Flight Permits Prohibited

(j) Under 14 CFR part 39.23, we are prohibiting special flight permits.

Alternative Methods of Compliance

(k) The Manager, Seattle Aircraft Certification Office, may approve alternative methods of
compliance for this AD if requested using the procedures found in 14 CFR 39.19.

My servo is a Precision RSA-5AD1, part # 2524054-11 but the AD Plug Gasket P/ N 365533 made differently since August 22, 2006. This makes me believe I am OK since my aircraft is a 1997 and I cannot find any fuel injection work in my logs but any inputs are appreciated.
Thanks
Bill

Since when did Continental start manufacturing all of those motors? Look at the bottom of the AD

And yes if your servo predates Aug 22, 2006, your OK as I interpret the AD, but you still must have a logbook entry saying your not affected by date of manufacture of your servo etc.
I can't see as how it could possibly hurt to try to turn the plug by hand though.

a64pilot · Post by **a64pilot** » Fri Mar 14, 2008 6:19 am

Question, oil changes are an owner maintenance thing, right? But to comply with the AD you have to have a certificated mechanic, right? If you have an affected Servo you have a 50 hour inspection or at every oil change, whichever occurs first that requires a certificated mechanic. Changing the gasket and increasing the torque does not get you out from under the inspection. Looks like a certificated mechanic will look at your servo at every oil change or 50 hours from now on.
Oh and don't be away from a maintenance facility when that 50th hour rolls around. "Special flights prohibited"
I think it will change so that changing the gasket and increasing the torque will get you out of the inspection, but that is only an opinion.

i just did 3 of these inspections this morning. IO-540, TIO-540, and LTIO-540. re-torque and re-safety wire. they all snugged up a bit, and one was suprisingly loose. it would be a very good idea to check yours.

1" socket
100 in/lbs
.025" safety

i put orange torque putty on ours for the future 50hr inspections. if the putty ain't broke, it's not loose. and while you're down there- when is the last time your injector servo fuel inlet screen was cleaned??????

UP-M5,
I just noticed that the 540 IO is not on the AD listing only the 320-D1B.
However the AD states that:
(1) Lycoming Engines IO, (L)IO, TIO, (L)TIO, AEIO, AIO, IGO, IVO, and HIO series
reciprocating engines, regardless of displacement, either new, rebuilt, overhauled, or repaired since
August 22, 2006, and/or with an affected fuel injection servo installed either new, rebuilt, overhauled,
or repaired since August 22, 2006.
I am going to check with the A&P who performed my engine work but does it appear you believe the 540IO should be inspected?
Thanks Bill

Something about the text part of the AD excerpt is funny...the engines listed as Continental are all Lycoming ones if I remember right.

Continental never made a 320, 540, etc.

The only one that I can remember Lycoming and Continental sharing displacement size with is the 360.

I looked up the FAA AD and it is a blanket AD covering all IO Lycomings and certain Continental 360's

This sort of makes sense because Continental often use their own injection system and Lycoming has been using the Bendix RSA system for years...

UP-M5 · Post by **UP-M5** » Fri Mar 14, 2008 5:39 pm

the AD really applies to any engine using a bendix type fuel injection system with the RSA-5 or RSA-10 fuel servos- doesn't matter what engine they are on.

Norm · Post by **Norm** » Mon Mar 17, 2008 5:06 pm

I received mine in the mail today and I notice that they are allowing re-use of the gasket P/N 365533 if it doesn't show signs of damage and just re-torque the nut to a higher value and get 50 hour inspections from here on. I find it strange that they would not require the use of the previous gasket but maybe not enough of them would be available in such a short period of time.

Or maybe they're confident the higher torque will solve the problem. It looks like the gasket in the FI systems before Aug 22, 2006 has the same P/N as the newer faulty gasket.

I'm Ok because my engine hasn't had any work done on the FI since Aug. 22, 2006 but must I have a logbook endorsement to that affect before I can fly again?

I finally got a chance to talk to my A& P and engine specialist. The engine tear down for the cam shaft, tappet valve lifter repair did not effect the fuel injector servo. All I needed was a log entry stating the above. Easy Fix.

The service bulletin PRS-107, Revision 2, which is dated after the emergency AD, states that this is a one time fix, to install a new gasket, # 2577258, which replaces the old gasket part #365533. torque and safety wire , then stamp the plug with the letter "G" and it is done for good. One time thing. No need for a mechanic to inspect every 50 hours. You can look up the service bullentin PRS-107, Revision 2 on Precision Air Motive website: www.precisionairmotive.com. We emailed them and they are mailing us a new gasket at no cost-70 cents if you buy it from Aviall, API or another distrubutor.

A service bulletin does not override an AD. You may have in fact fixed the problem, but you still have to comply with the AD.
On edit: If the FAA buy's off that the SB is a "terminating action" then expect the AD to be revised to say that if you comply with the SB, then you have terminated the AD. In other words no 50 hour insp. by an A&P, but until that happens, if you are affected by the AD, then you are stuck to the insp. interval by a qualified mechanic.

Green Hornet · Post by **Green Hornet** » Thu Mar 27, 2008 1:16 pm

Since the elctronice version of the AD calls out PRS-107, Revision 1, dated March 6, 2008 as an alternative method of compliance para (l) it could be interpreted to be part of the AD. However for confirmation contact Carol Key Manager of Seattle FAA 425 277-2657 for clarification to be on the safe side.

The elctronic version of the AD states the following:
Alternative Methods of Compliance :

(k) The Manager, Seattle Aircraft Certification Office, may approve alternative methods of
compliance for this AD if requested using the procedures found in 14 CFR 39.19.
Related Information :

http://www.faa.gov/airports_airtraffic/ ... n/seattle/

(l) Precision Airmotive LLC Mandatory Service Bulletin No. PRS-107, Revision 1, dated
March 6, 2008, pertains to the subject of this AD. You can get the service information identified in
this AD from http://www.precisionairmotive.com.

If it's an AMOC, then it's legal, period. You don't need to call, but it never hurts. I missed the AMOC. Funny too because I contacted Precision Airmotive and spoke to their product support. If their SB was an AMOC, he should have said so.
I'm not affected and threw my copies of the AD away, but I didn't notice an AMOC.
I just looked at the copy posted, and I still don't see an approved AMOC.
