Airworthiness Directive 2017-17-10
one-timeAirworthiness Directives; ATR-GIE Avions de Transport Régional Airplanes
What this AD requires
We are superseding Airworthiness Directive (AD) 2015-23-12, which applied to all ATR-GIE Avions de Transport R[eacute]gional Model ATR42 and ATR72 airplanes. AD 2015-23-12 required identifying the serial number and part number of the main landing gear (MLG) rear hinge pins, and replacing pins or the MLG if necessary. This AD retains the requirements of AD 2015-23-12, requires replacing certain additional MLG hinge pins, and reduces certain compliance times. This AD was prompted by a new occurrence of a cracked MLG rear hinge pin. We are issuing this AD to address the unsafe condition on these products.
Which aircraft AD 2017-17-10 applies to
Whether AD 2017-17-10 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.
