Airworthiness Directive 2016-25-01
one-timeAirworthiness Directives; The Boeing Company Airplanes
What this AD requires
We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 747-400, 747-400D, and 747-400F series airplanes; Model 757 airplanes; and Model 767-200, -300, -300F, and - 400ER series airplanes. This AD was prompted by reports of uncommanded autopilot engagement events resulting in incorrect stabilizer trim adjustment during takeoff. This AD requires, depending on the model/ configuration, installing an on-ground stabilizer autotrim inhibit system, relays and related wiring to open and close the flight control computer (FCC) analog output, and new operational program software (OPS) into the FCCs. We are issuing this AD to address the unsafe condition on these products.
Which aircraft AD 2016-25-01 applies to
Multi-model AD: (1) 747-400/-400D/-400F per SASB 747-22-2256 R1; (2) 757-200/-200PF/-200CB/-300 per SASB 757-22-0096 R1; (3) 767-200/-300/-300F/-400ER per SASB 767-22-0143 R2, excluding certain winglet-equipped 767-300/-300F airplanes under STC ST01920SE identified in APB SB AP767-22-005 R1; (4) 767-300/-300F per SASB 767-22-0146 R1; (5) winglet-equipped 767-300/-300F airplanes under STC ST01920SE with P/N 2276-COL-AF2-03 per APB SB AP767-22-005 or Revision 1.
Whether AD 2016-25-01 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.
