## Abstract

This amendment adopts a new airworthiness directive (AD), applicable to certain Saab Model SAAB 340B series airplanes, that requires a one-time inspection for moisture or other contamination of a certain wiring harness, electrical relay, and relay socket; a one-time inspection for electrical damage of the same electrical relay and socket; corrective actions, if necessary; and replacement of certain nut plates with new, improved parts. 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 a short circuit caused by fluid leakage, which could result in inability to retract the landing gear or require the use of emergency extension.
