Models named: F27 Mark 200, 400, 500, 600. Read the applicability below — it usually turns on serial or part numbers too.
Applicability*9
This AD applies to Fokker Model F27 Mark 200, 400, 500, and 600 airplanes, certificated in any category; serial numbers 10505 through 10591 inclusive; not equipped with inboard wing fuel tanks.
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. Inspection and Corrective Action if Applicable (f) Within 3 months after the effective date of this AD, do a general visual inspection of the rotary knobs for the fuel tank isolation valves to determine if the seal wire is installed correctly and do the corrective action(s) as applicable, in accordance with the Accomplishment Instructions of Fokker Service Bulletin F27/28-67, dated February 23, 2004. Do the applicable corrective actions before further flight. Note 1: For the purposes of this AD, a general visual inspection is: “A visual examination of an interior or exterior area, installation, or assembly to detect obvious damage, failure, or irregularity. This level of inspection is made from within touching distance unless otherwise specified. A mirror may be necessary to ensure visual access to all surfaces in the inspection area. This level of inspection is made under normally available lighting conditions such as daylight, hangar lighting, flashlight, or droplight and may require removal or opening of access panels or doors. Stands, ladders, or platforms may be required to gain proximity to the area being checked.” Credit for Alternative Method of
Unsafe condition
This AD was prompted by investigation of a recent accident, which found that the rotary knobs controlling the fuel tank isolating valves had been in the shut position. We are issuing this AD to ensure that the rotary knobs are not inadvertently moved to the shut position, which could result in fuel starvation to both engines and consequent inability to maintain controlled flight and landing.
