Airworthiness Directive 2009-26-06 Summary
Summary:
The FAA is superseding an existing airworthiness directive (AD) for Honeywell International Inc.
ALF502 series and LF507 series turbofan engines with certain fuel manifold assemblies installed.
That AD currently requires initial and repetitive on-wing eddy current or in-shop fluorescent
penetrant inspections of certain part number (P/N) fuel manifold assemblies for cracks, and
replacement of cracked fuel manifolds with serviceable manifolds. This AD continues to require
inspecting those fuel manifolds for cracks, adds leak checks of certain additional P/N fuel
manifolds, and specifies replacement of the affected manifolds as an optional terminating action
in lieu of the repetitive inspections. This AD results from reports of fire in the engine nacelle. We
are issuing this AD to detect cracks in certain fuel manifolds and fuel leaks from other fuel
manifolds, which could result in a fire in the engine nacelle and a hazard to the aircraft.

Adoption of the Amendment
Accordingly, under the authority
delegated to me by the Administrator,
the Federal Aviation Administration
amends 14 CFR part 39 as follows:
Compliance
(e) You are responsible for having the
actions required by this AD performed within
the compliance times specified unless the
actions have already been done.
Initial Inspection for Fuel Leaks, Fuel
Manifold Assemblies, P/Ns 2–163–620–37 or
2–163–620–38
(g) For fuel manifold assemblies, P/Ns 2–
163–620–37 or 2–163–620–38, with 1,800 or
more CSN or cycles-since-overhaul (CSO),
inspect for leaks within 300 CIS after the
effective date of this AD as follows:
(1) Start engine and let stabilize at ground
idle.
(2) With the engine operating, look for fuel
leaking from the fuel manifold assembly to
the fire shield interface area (see Figure 1 of
this AD). No leaks allowed.
(3) If you find any leaks, shutdown the
engine and replace the fuel manifold
assembly with an FAA-approved serviceable
assembly.
(4) Shut down engine.
(5) Look for fuel leaking from the fuel
manifold assembly to the fire shield interface
area (see Figure 1 of this AD). No leaks
allowed.
(6) If you find any leaks, replace the fuel
manifold assembly with an FAA-approved
serviceable assembly.
