Airworthiness Directive 01-16203
one-timeAirworthiness Directives; Gulfstream Model G-1159, G-1159A, G-1159B, G-IV, and G-V Series Airplanes
What this AD requires
This amendment corrects and clarifies information in an existing airworthiness directive (AD), applicable to certain Gulfstream Model G-1159, G-1159A, G-1159B, G-IV, and G-V series airplanes, that currently requires an inspection to determine if certain door control valves of the landing gear are installed, and modification of the valve, if necessary. The actions specified in that AD are intended to prevent loss of hydraulic system fluid due to failure of the door control valve of the landing gear, which could require the flight crew to use alternate gear extension procedures (landing gear blow down) for landing of all models. This amendment corrects the requirements of the current AD by specifying appropriate alert customer bulletins for certain airplane models, and clarifying the compliance time for the modification of the door control valve of the landing gear. This amendment is prompted by operators' comments on the existing AD.
Which aircraft AD 01-16203 applies to
Whether AD 01-16203 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.
