The airworthiness directive

84-25-04 BOEING: Amendment 39-4968. Applies to all Boeing Model 747 airplanes equipped with Landing Rollout Control Unit automatic landing systems, Boeing P/N 60B00013-757 or 60B00013-759.

To prevent a hazardous condition due to loss of the autopilot battery power, within 30 days after the effective date of this AD install a placard on the autopilot P10 mode select panel which reads as follows: "DO NOT USE THE LAND MODE," unless already accomplished. The placard may be removed when the airplane wiring has been modified in accordance with Boeing Service Bulletin 747-22A2152, dated November 16, 1984, or later FAA approved revision; or any alternate means of compliance which provides an equivalent level of safety approved by the Manager, Seattle Aircraft Certification Office, FAA, Northwest Mountain Region.

All persons affected by this proposal who have not already received the Service Bulletin may obtain copies upon request to Boeing Commercial Airplane Company, P.O. Box3707, Seattle, Washington 98168. These documents may also be examined at the FAA, Northwest Mountain Region, 9010 East Marginal Way South, Seattle, Washington.

This amendment becomes effective January 2, 1985.
