This action makes a correction to Airworthiness Directive (AD) 95-24-13 concerning Jetstream Aircraft Limited (JAL) HP137 Mk1, Jetstream Series 200, and Jetstream Models 3101 and 3201 airplanes, which published in the Federal Register on December 22, 1995 (60 FR 246). That publication incorrectly references the number of aileron mounting spigot nut assemblies to be replaced on the wings of the airplanes. The AD currently requires ``replacing the securing nut assemblies and split pins with new special nut assemblies (Part No. SL5022 (Qty. 2))''. The intent of the AD is to require replacement of 2 special nut assemblies on each wing, for a total of 4 nut assemblies. The Final Rule AD did not specify ``each wing'', and stated that only 2 nut assemblies rather than 4 nut assemblies are required. This action corrects the AD to reflect this change.

A correction restates part of an AD that was published incorrectly. It is not an additional requirement and it does not change the AD number or its effective date.

Full official abstract

This amendment adopts a new airworthiness directive (AD) that applies to Jetstream Aircraft Limited (JAL) HP137 Mk1, Jetstream Series 200, and Jetstream Models 3101 and 3201 Airplanes. This action requires inspecting (one-time) the threaded portion of the aileron mounting spigots for cracks, replacing any cracked spigots, and replacing the securing nut assemblies with newly designed special nut assemblies and new split pins. Reports of cracked aileron mounting spigots caused by stress corrosion prompted this action. The actions specified by this AD are intended to prevent damage to the aileron control systems, which if not detected and corrected, could cause loss of lateral control and eventual loss of control of the airplane.
