Airworthiness Directive 2014-16-15
recurringAirworthiness Directives; Turbomeca S.A. Turboshaft Engines
What this AD requires
We are adopting a new airworthiness directive (AD) for certain Turbomeca S.A. Makila 2A and Makila 2A1 turboshaft engines. This AD requires initial and repetitive visual inspections, and replacement of the splines of the high-pressure (HP) fuel pump/metering valve and the module M01 drive gear, if necessary. This AD was prompted by the failure of two HP fuel pumps that resulted in engine in-flight shutdowns. We are issuing this AD to prevent failure of the HP fuel pump, which could lead to an in-flight shutdown, damage to the engine, and forced landing or accident.
Which aircraft AD 2014-16-15 applies to
Applies only when high-pressure (HP) fuel pump P/N 0 298 91 806 0 or 0 298 91 805 0 is installed and Turbomeca modification TU 59 has not been incorporated.
Whether AD 2014-16-15 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.
