Reason: The Jetstream J41 Aircraft Maintenance Manu al (AMM), includes the following chapters: 05-10-10 “Airworthiness Limitations”, 05-10-20 “Certification Maintenance Requirements”, and, 05-10-30 “Critical Design Configuration Control Lim itations (CDCCL) – Fuel System”.
The maintenance tasks and limitations contained in these chapters have been identified as mandatory actions for continued airwo rthiness and EASA issued AD 2010-0098 to require operators to comply with th ose instructions. Since that AD was issued, BAE Systems (Operations) Ltd issued Revision 37 of the AMM amending Chapter 05-10-10 to revise and reduce the life limit of certain main landing gear components. In addition, Revision 38 of the AMM was issued to amend Chapters 05-10-00 and 05-10-10 introducing inspections to be accomplished after implementation of some rep airs affecting fatigue strength of critical structure. Failure to comply w ith the new and more restrictive actions could result in an unsafe condition. For the reasons described above, this AD, which sup ersedes EASA AD 2010-0098, requires implementation of the maintenan ce requirements and/orEASA AD No.: 2014-0043
