REGULATORY TEXT:   88-17-02 R2 FOKKER: Amendment 39-6035 as revised by Amendment 39-6127 is further revised by Amendment 39-6331. Docket No. 89-NM-82-AD.

Applicability: Model F-27 series airplanes, serial numbers 10346 to 10684, inclusive; and serial numbers 10105 to 10345, inclusive, if retrofitted with outerwing serial number 246 or higher; certificated in any category.

Compliance: Required as indicated unless previously accomplished.

To prevent reduced structural capability of the wing, accomplish the following:

A. Within 24 hours after February 15, 1989 (the effective date of Amendment 39- 6127), incorporate the following into the Limitations Section of the Airplane Flight Manual (AFM). This may be accomplished by inserting a copy of this AD into the AFM.

"For airplanes operating at weights over 32,000 lbs.:
Speed Limitation VB: 165 KIAS (168 KTS CAS)"

B. Within 24 hours after February 15, 1989 (the effective date of Amendment 39- 6127), install a placard near each airspeed indicator, stating the following:

FOR AIRPLANES OPERATING AT WEIGHTS OVER 32,000 LBS.:
SPEED LIMITATION VB: 165 KIAS (168 KTS CAS)

C. Within six months after the effective date of this amendment, perform a one-time inspection of the splice parts at Wing Station 7915, in accordance with the Accomplishment Instructions, Part 1, Fokker Service Bulletin F27/57-63, Revision 1, dated January 25, 1989.

1. If no defective splice parts are found, and if the structural strength of the wing splice is determined to be satisfactory in accordance with the limits specified in the service bulletin, no further action is required. The airspeed restriction required by paragraphs A. and B., above, is no longer required, and the AFM limitation and placard may be removed.

2. If defective splice parts are found or if the structural strength of the wing splice is determined to be unsatisfactory in accordance with the limits specified in the service bulletin, within one year after the effective date of this amendment reinforce all unsatisfactory splice parts at Wing Station 7915 in accordance with the Accomplishment Instructions, Part 2, of Fokker Service Bulletin F27/57-63, Revision 1, dated January 25, 1989. Following this modification and a determination that the wing splice strength is satisfactory, the airspeed restriction required by paragraphs A. and B., above, is no longer required, and the AFM limitation and placard may be removed.

D. An alternate means of compliance or adjustment of the compliance time, which provides an acceptable level of safety, may be used when approved by the Manager, Standardization Branch, ANM-113, FAA, Northwest Mountain Region.

NOTE: The request should be forwarded through an FAA Principal Maintenance Inspector (PMI), who will either concur or comment and then send it to the Manager, Standardization Branch, ANM-113, FAA, Northwest Mountain Region.

E. Special flight permits may be issued in accordance with FAR 21.197 and 21.199 to operate airplanes to a base in order to comply with the requirements of this AD.

All persons affected by this directive who have not already received the appropriate service documents from the manufacturer may obtain copies upon request to Fokker Aircraft USA, Inc., 1199 N. Fairfax Street, Alexandria, Virginia 22314. These documents may be examined at FAA, Northwest Mountain Region, Transport Airplane Directorate, 17900 Pacific Highway South, Seattle, Washington, or Seattle Aircraft Certification Office, 9010 East Marginal Way South, Seattle, Washington.
