What to do
Operators must inspect the sliding member extension within 500 flight cycles of 15 November 2007 and every 500 cycles thereafter until corrective actions are completed. Lockwiring must be checked and installed within 4000 flight hours of the effective date. Any findings of overextension or incorrect lockwiring must be reported to Fokker Services. After 1 May 2008, only main landing gear units with proper lockwiring may be installed as spares.
Summary
EASA Safety Information Notice No. 2007-39 Revision 1 and Civil Aviation Authority Netherlands Airworthiness Directive NL-2007-002 address the main landing gear sliding member end-stop installation on Fokker F27 Mark 050, Mark 0502, and Mark 0604 series aircraft. The documents highlight a safety concern due to improper installation leading to potential overextension of the main landing gear sliding member. These publications provide inspection and corrective action requirements to ensure proper lockwiring and prevent structural damage.
What changed
This is a new Airworthiness Directive requiring inspections for the presence and correct installation of lockwiring on the lockbolts securing the main landing gear sliding member end-stop. It mandates measuring the sliding member extension within specified flight cycles and installing lockwiring if missing. Additionally, it prohibits installation of spare main landing gear units without proper lockwiring after a specified date.
Why it matters
This directive is critical for aviation professionals because failure to comply may lead to structural damage of the main landing gear and loss of aircraft control during landing. Operators and maintenance organizations must ensure compliance to maintain aircraft airworthiness and safety. The directive also affects maintenance scheduling and spare parts management.
