Airworthiness Directive 97-20-11
one-timeAirworthiness Directives; SocataGroupe Aerospatiale Model TBM 700 Airplanes
What this AD requires
This amendment adopts a new airworthiness directive (AD) that applies to certain Socata--Groupe Aerospatiale (Socata) Model TBM 700 airplanes. This AD requires removing the main landing gear (MLG) inboard doors and the door locking control mechanism (MOD 70-065-32). This AD is the result of an incident on one of the affected airplanes where the MLG inboard door locking hooks (hinges) corroded, caused the doors to jam, and prevented the MLG from extending. The Federal Aviation Administration's analysis reveals that removing the MLG inboard doors will not cause any airplane safety or performance problems. The actions specified by this AD are intended to prevent the MLG from failing to extend because of corroded MLG inboard locking hinges, which could result in loss of control of the airplane during landing operations.
Which aircraft AD 97-20-11 applies to
Specific model/serial applicability list is in the preceding applicability provision, not present in this excerpt. Requires removing the MLG inboard doors and door locking control mechanism (MOD 70-065-32) per Socata Service Bulletin 70-073, Amendment 1, to prevent corroded MLG inboard locking hinges causing gear-extension failure; reinstalling the removed mechanism is prohibited.
Whether AD 97-20-11 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.
