Compliance
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
Required actions
This paragraph restates the requirements of paragraph (a) of AD 94-14-05, Amendment 39-8957 (59 FR 35237, July 11, 1994). For airplanes having serial numbers 11443, 11446 through 11449 inclusive, and 11456: Within 30 days after August 10, 1994 (the effective date of AD 94-14-05), remove the actuator from the FBTV, part number (P/N) 7933141J and install a locking device on the FBTV, in accordance with the Accomplishment Instructions of Fokker Service Bulletin SBF100-28-029, Revision 1, dated November 30, 1993.
Unsafe condition
This AD was prompted by reports that the fuel-balance transfer-valve (FBTV) was inadvertently reactivated after required de-activation measures were undone. We are issuing this AD to prevent fuel starvation and a consequent double-engine flameout, possibly resulting in a forced landing, damage to the airplane, and injury to occupants.
Affected ADs
This AD supersedes AD 94-14-05, Amendment 39-8957 (59 FR 35237, July 11, 1994); and AD 96-07-06, Amendment 39-9555 (61 FR 14014, March 29, 1996).
