(a) Inspect each exit internal and external handle cover installation and determine that NAS 43DD3-8 spacers, 0.12 inches long, are installed as illustrated in BHTI Service Bulletin No. 214-77-1 as in force from time to time.(b) Add one-inch diameter inspection holes in the right and left side passenger door assemblies in accordance with BHTI Service Bulletin No. 214-77-4 as in force from time to time. Provide a clear view of those holes through any interior lining.(c) Label each of these inspection holes using stencils as noted in BHTI Service Bulletin No. 214-77-4 as in force from time to time, or use CASA or FAA approved equivalent placards, labels, or stencils located adjacent to each hole on the interior skin or lining, if installed.2. (a) Inspect the latch mechanism of each passenger exit door and adjust as necessary to make each pin end flush with the exit frame edge, when the mechanism is in the fully unlatched position, as prescribed in BHTI Service Bulletin No. 214-76-4 as in force from time to time.(b) Inspect for and, unless previously accomplished, add a painted stripe around the cylinder part of each pin using white or other contrasting colour.Note 1: STC SH2769SW has such an exit design.Note 2: The words “as in force from time to time” require compliance with the most recent version of the referenced document.Note 3: FAA AD 77-17-05 refers. |\n\n| Compliance: | 1.
