Unsafe Condition
Erroneous braking performance information in the Airplane Flight Manual (AFM) could cause possible runway overshoot during certain runway-limited takeoffs or landings.
AI-generated summary from the source AD text. Verify against the official source before acting.
Required Actions
Amend the FAA-approved AFM documents (D6T11320 and D6T11321) by either incorporating specified revisions (D6T11320.222 Rev 13, D6T11320.231 Rev 13, D6T11321.223 Rev 16, D6T11321.232 Rev 16, or Rev 2 to Appendix 8F to D6T11321) or adjusting takeoff speeds, takeoff performance-limited weights, and landing field lengths as detailed in the directive. Compliance may be achieved through alternate means approved by the FAA.

ADDRESSES: FOR FURTHER INFORMATION CONTACT: SUPPLEMENTARY INFORMATION: REGULATORY TEXT: 87-03-07 BOEING: Amendment 39-5523. Applies to Boeing Model 767-200 airplanes equipped with Bendix brakes, Part Numbers 2607092-1 and -2, certificated in any category. To preclude possible runway overshoot during certain runway-limited takeoffs or landings, due to erroneous braking performance information in the Airplane Flight Manual (AFM), accomplish either paragraph A. or B., below, within 30 days after the effective date of this AD, unless already accomplished. A. Amend the applicable FAA-approved AFM's, Boeing Documents D6T11320 and D6T11321, to include the information contained in subject FAA-approved revisions below: D6T11320.222, Revision 13; D6T11320.231, Revision 13; D6T11321.223, Revision 16; D6T11321.232, Revision 16; Revision 2 to Appendix 8F to D6T11321; or B. Amend the applicable FAA-approved AFM's, Boeing Documents D6T11320 and D6T11321, by incorporating the following performance adjustments: 1. TAKEOFF SPEEDS - Pre-correction (original) V1 speeds are reduced by two (2) knots for gross weights of 280,000 lbs. and greater, and by one (1) knot for gross weights below 280,000 lbs. 2. TAKEOFF PERFORMANCE-LIMITED WEIGHTS - Pre-correction FIELD LENGTH LIMITS weights are reduced by: FIELD LENGTH LIMITED WEIGHT 1000 LBS. WEIGHT DECREMENT (LBS.) FOR FLAP POSITION SHOWN 1 5 15 20 380 & Above 4900 4900 4400 4500 360 4600 4700 4400 4300 340 4300 4500 4300 4000 320 4000 4100 4000 3600 300 3600 3500 2600 2500 280 2800 2100 1300 1300 260 1200 1100 1200 1200 240 & Below 1000 1100 1200 1200 To determine corrected runway length (as in obstacle clearance calculations), increase gross weight by the above amounts before entering the FIELD LENGTH LIMITS chart. 3. LANDING FIELD LENGTH LIMITS - For gross weights above 280,000 lbs., landing field length required is increased by 900 feet over the pre-correction value. For gross weights of 280,000 lbs. and below, the landing field length required is increased by 350 feet over the pre-correction value. C. 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, Seattle Aircraft Certification Office, FAA, Northwest Mountain Region. All persons affected by this directive who have not already received copies of the Airplane Flight Manual performance information may obtain copies upon request to the Boeing Commercial Airplane Company, P.O. Box 3707, Seattle, Washington 98124-2207. These documents may be examined at the FAA, Northwest Mountain Region, 17900 Pacific Highway South, Seattle, Washington, or the Seattle Aircraft Certification Office, 9010 East Marginal Way South, Seattle, Washington. This amendment becomes effective February 26, 1987. FOOTER:
