Airworthiness Directive 2002-19-02
one-timeAirworthiness Directives; Turbomeca S.A. Makila Models 1A, 1A1, and 1A2 Turboshaft Engines
What this AD requires
This amendment adopts a new airworthiness directive (AD) that is applicable to Turbomeca S.A. Makila Models 1A, 1A1, and 1A2 turboshaft engines with exhaust pipes incorporating modification TU 200A installed. This action requires visual inspections of exhaust pipes for cracks and tears, upon completion of the last flight of each day, and replacement of cracked and torn exhaust pipes before further flight. This action also requires removal from service of modification TU 200A exhaust pipes at the next shop visit or no later than a certain date. This amendment is prompted by several reports of modification TU 200A exhaust pipes cracking at several of the ejector attachment tabs. The actions specified in this AD are intended to prevent the ejector from becoming loose from the exhaust pipe, resulting in damage to the main rotor and tail rotor and loss of helicopter control.
Which aircraft AD 2002-19-02 applies to
AD requires daily visual inspection of exhaust pipe ejector attachment tabs for cracks/tears (mirror inspection required on pipes with modification TU 54), immediate replacement before further flight upon crack/tear detection, and post-replacement engine vibration checks. Terminating action: remove exhaust pipes incorporating modification TU 200A from service by 2003-06-30 or next shop visit, per Turbomeca ASB No. A298 72 0148 Update 1 (2002-02-18).
Whether AD 2002-19-02 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.
