Project MS 13/16 - Proposed Instrument to mandate inspection of Control Cable Assemblies with terminals manufactured from SAE-AISI 303 Se stainless steel
Project closed 5 February 2015.
AD/GENERAL/87 has been published, requiring replacement of primary flight control cable assemblies using terminals constructed of SAE-AISI 303 Se or SAE-AISI 304 stainless steel, once total time in service is 15 years.
The AD does not apply to aircraft maintained to MSG-3 methodology or those with continuing airworthiness life limits for primary flight control cable assemblies that are less than 15 year total time in service.
CASA has received a number of Service Difficulty Reports from aircraft operators on control cable fitting failures. The control cable terminals were manufactured from SAE-AISI 303 Se, had been in service for 15 years or more and failed due to stress corrosion cracking.
The objective of the project is to issue an Notice of Proposed Rule Making (NPRM) detailing CASA's proposed plan about issuing an Airworthiness Directive which would seek to mandate a recurring inspection, applicable to control cable terminals manufactured from SAE-AISI 303 Se, which have a total time in service of greater than, or equal to, 15 years.
This project was approved by: Peter Boyd, Executive Manager Standards Division on 11 June 2013.
