Airworthiness Directives; Saab AB, Saab Aerosystems Airplanes

What this AD requires

We are superseding an existing airworthiness directive (AD) for all Saab AB, Saab Aerosystems Model 340A (SAAB/SF340A) and SAAB 340B airplanes. That AD currently requires an inspection of the main landing gear (MLG) separation bolt harness for broken wires and corroded connectors, and corrective actions if necessary; and for certain airplanes, a modification of the MLG separation bolt's electrical harness. This new AD requires replacement of the separation bolt harness. This AD was prompted by reports of broken wires and corroded connectors in the SAAB 340 MLG emergency release system. We are issuing this AD to prevent improper release of the MLG during an emergency situation, possibly resulting in damage to the airplane during landing and injury to the occupants.

Model 340A also identified as SAAB/SF340A. Applies to all serial numbers.

Whether AD 2011-27-05 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.

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.
