Airworthiness Directive 98-26392

recurring
AD 98-26392 · 1998-10-06 · airframe

Airworthiness Directives; Short Brothers Model SD3-30, SD3-60, SD3-60 SHERPA, and SD3 SHERPA Series Airplanes

What this AD requires

This amendment adopts a new airworthiness directive (AD), applicable to all SD3-30, SD3-60, SD3-60 SHERPA, and SD3 SHERPA series airplanes, that requires repetitive visual inspections of the flap levers and bracket assembly of the inner flap sub-assembly of the left and right wings to detect certain discrepancies; and corrective actions, if necessary. This amendment is prompted by mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified by this AD are intended to detect and correct failure of the levers and bracket assembly, which could result in uncommanded retraction of the inner flap assembly and consequent reduced controllability of the airplane.

Repetitive inspection. Re-inspect. The next-due date/hours depend on this aircraft’s time in service — a records report computes it from the logbooks.

Whether AD 98-26392 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 98-26392 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.
