Applies to: Model MU-2B-36 aircraft serial numbers 675, 681, 684, 687, 688, 691, and 695; models MU-2B-36A, and MU-2B-60, serial numbers 697SA, 699SA, 701SA, 706SA, 708SA, 709SA, 711SA, 713SA, 714SA, 719SA, 720SA, 721SA, 723SA, 725SA, 727SA, 729SA through 736SA, 738SA through 747SA, 749SA through 757SA, 759SA, 761SA, 763SA and 765SA.

Compliance is required within the next 25 hours of flight time, after the effective date of this AD, unless already accomplished.

To assure a reliable attitude reference and retain eligibility for IFR operation, install an improved avionic equipment mounting shelf in accordance with: (1) Mitsubishi Aircraft International Service Note No. 062 dated November 30, 1979, on affected Serial Number MU- 2B-36 aircraft, or (2) Mitsubishi Aircraft International Service Bulletin SB015/53-001 dated November 30, 1979, on affected serial number MU-2B-36A and MU-2B-60 aircraft.

If the improved avionic equipment mounting shelf is not installed within the 25 hour compliance period, aircraft operations are limited to day VFR only. In this event install a placard stating "OPERATIONS LIMITED TO DAY VFR" with letters a minimum of 1/4 inch high in clear view on the pilot's instrument panel. The placard and limitation can be removed upon incorporation of the improved avionic equipment shelf.

The manufacturer's instructions identified and described in this directive are incorporated herein and made a part hereof pursuant to 5 U.S.C. 552(a)(1). All persons affected by this directive who have not already received these documents from the manufacturer may obtain copies of the Service Bulletin or Service Note upon request to Mary Ann Lowry, Publications Group, Mitsubishi Aircraft International, P.O. Box 3848, San Angelo, Texas 76901; telephone (915) 944-1511, extension 269; Telex 73-9438.

These documents may also be examined at the Office of the Regional Counsel, Southwest Region, FAA, 4400 Blue Mound Road, Fort Worth, Texas, and at FAA Headquarters, 800 Independence Avenue, S.W., Washington, D.C. A historical file on this AD which includes the incorporated material in full is maintained by the FAA at its headquarters in Washington, D.C., and at the Southwest Regional Office in Fort Worth, Texas.

This amendment becomes effective February 14, 1980.
