## The airworthiness directive

67-03-05 LOCKHEED: Amdt. 39-326 Part 39 Federal Register December 22, 1966. Applies to Models 649, 749, and 1049 Airplanes Powered by Wright 749C18BD-1 and 975C18CB-1 Engines Equipped With Hamilton Standard 43E60/6869-0, 43E60/6901-0, and 43E60/6903-0 Propellers.

Compliance required within the next 200 hours' time in service after the effective date of this AD, unless already accomplished.

To minimize propeller vibratory stresses, amend the FAA-approved Airplane Flight Manual to include the following operating limitations:

Continuous ground running between 2,300 and 2,650 r.p.m. with the propeller governing is prohibited.

Continuous static ground running in a crosswind above 2,650 r.p.m. is prohibited.

This directive effective January 23, 1967.
