Plain English Summary

4/10 complexity

This Airworthiness Directive requires replacement of flight‑deck escape ropes (and cabin ropes if fitted) using specified Fokker Service Bulletins and adds a Maintenance Schedule task to discard ropes after six years. It applies to all Fokker F27 Mk 050, Mk 0502 and Mk 0604 aircraft and must be done within one calendar year after 12 May 2005. The measure responds to reports of cracks and reduced tensile strength in the cast cotton/polyester escape‑rope assemblies that could render them unusable in an evacuation.

Fokker F50 (F27 Mk 50) Series Aeroplanes

AD/F50/90	Escape Ropes	5/2005

Applicability:	All Model F27 Mk 050, Mk 0502, and Mk 0604 aircraft.
Requirement:	1. Replace affected escape ropes with serviceable parts in accordance with the Accomplishment Instructions of Fokker Services Service Bulletin F50-25-059, dated 28 June 2004, or later CAA-NL approved revision (for flight deck escape ropes); or Service Bulletin TASBF50-25-903, dated 4 October 2004, or later CAA-NL approved revision (for cabin escape ropes, only present in some special mission aircraft configurations).2. Amend the aircraft’s Maintenance Schedule to include a new discard task for the escape ropes after each 6 years time in service.Note: CAA-NL AD 2004-159 refers.
Compliance:	For Requirements 1 and 2: Within one calendar year after 12 May 2005.
	This Airworthiness Directive becomes effective on 12 May 2005.
Background:	Reports have been received from operators of small cracks evident in the polyester block into which the cotton flight deck escape rope is cast. A repair was subsequently carried out and a tensile test was performed. The results established that these ropes had deteriorated over time and their load-bearing capability had been considerably reduced. This condition, if not corrected, could lead to escape ropes failing or becoming unusable during an emergency evacuation.
