Airworthiness Directive 02-16176
one-timeAirworthiness Directives; CFE Company Model CFE738-1-1B Turbofan Engines
What this AD requires
This amendment revises an existing airworthiness directive (AD), that is applicable to CFE Company Model CFE738-1-1B turbofan engines. That AD currently requires a one-time visual inspection of stage 2 high pressure turbine (HPT) aft cooling plates for nicks, dents, raised metal, and scratches, and if necessary, repair of the cooling plates or replacement with serviceable parts. This amendment reduces the number of stage 2 HPT aft cooling plates affected by AD 99- 27-16, and identifies the applicable engines by engine serial numbers (SN's). This amendment is prompted by an updated alert service bulletin (ASB) that reduces the number of stage 2 HPT aft cooling plates affected by AD 99-27-16 and identifies the applicable engines by engine SN's. The actions specified by this AD are intended to prevent stage 2 HPT aft cooling plate failure, which could result in an uncontained engine failure and damage to the airplane.
Which aircraft AD 02-16176 applies to
Applies to stage 2 HPT aft cooling plate and stage 2 HPT rotor disk post; inspect/repair/replace at next shop visit affording access, not later than 4,500 cycles-since-new, per CFE ASB CFE738-A72-8031 Rev 4.
Whether AD 02-16176 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.
How AD compliance is recorded
A valid compliance record (14 CFR 43.9) states:
Tailplate reads a tail number’s logbooks and matches every applicable AD — including this one — to its compliance evidence, with recurring next-due dates computed.
