Airworthiness Directive 04-15510
one-timeAirworthiness Directives; Israel Aircraft Industries, Ltd., Model 1121, 1121A, 1121B, 1123, 1124, and 1124A Series Airplanes
What this AD requires
This amendment adopts a new airworthiness directive (AD), applicable to all Israel Aircraft Industries, Ltd., Model 1121, 1121A, 1121B, 1123, 1124, and 1124A series airplanes, that requires a one-time inspection to detect cracking and other discrepancies of both sides of the rudder skins and ribs, forward to aft on each spar, to detect cracks below the skin surface; and corrective action if necessary. This action is necessary to detect and correct cracking of the skins of the rudder assembly, which could result in reduced structural capability of the rudder and reduced controllability of the airplane. This action is intended to address the identified unsafe condition.
Which aircraft AD 04-15510 applies to
applicability derived from the AD summary — confirm the model/serial from the records
Whether AD 04-15510 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.
