Airworthiness Directives; Israel Aircraft Industries, Ltd. (IAI), Model 1124 and 1124A Series Airplanes

What this AD requires

This amendment adopts a new airworthiness directive (AD), applicable to all IAI Model 1124 and 1124A series airplanes, that requires installation of an independent circuit breaker and associated wiring changes for the hydraulic low pressure warning lights. This amendment is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified by this AD are intended to prevent loss of the hydraulic low pressure warning lights. Low pressure in the hydraulic system can result in reduced controllability of the airplane.

applicability derived from the AD summary — confirm the model/serial from the records

Whether AD 99-22387 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:

Method of compliance — The specific action taken (inspected, replaced, modified) and to what revision.

Date — When the work was done.

Aircraft time — Total time in service / tach at compliance — how recurring next-due is computed.

Signature & certificate — The A&P/IA who returned it to service, with certificate number.

Is AD 99-22387 complied with on your aircraft?

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.

Applicability is derived from the FAA directive corpus and is advisory, not a legal airworthiness determination. Compliance is established only from an aircraft’s actual records.
