## The airworthiness directive

64-03-03 HAMILTON STANDARD: Amdt. 678 Part 507 Federal Register January 29, 1964. Applies to All Hamilton Standard Aluminum-Alloy Propeller Blades. (Aircraft on Which These Propeller Blades are Installed Include but are not Necessarily Confined to the Boeing 377; Convair 240, 340, 440; Douglas DC3 Series, DC-6, DC-6A, DC-6B, DC-7, DC-7A, DC-7B, DC- 7C; Lockheed 049 749A, 1049/C/D/G/H, 1649A; and Martin 202A, 404.)

Compliance required as indicated.

For all aluminum-alloy propeller blades exposed to known or suspected impact with solid objects (blades static or rotating), the following shall be accomplished:

  (a) Non-surface-treated blades shall be inspected in accordance with the applicable Hamilton Standard Bulletins and Service Manuals. If repair of damage requires procedures that include bending or twisting, the blade shall be removed and repaired before further flight. Other damage may be repaired without blade removed in accordance with the applicable Hamilton Standard instructions.

  (b) Surface-treated blades as classified in Hamilton Standard Bulletin No. 596B shall be inspected in accordance with the applicable Hamilton Standard Bulletins and Service Manuals.

  (1) Blades with visual evidence of bending, twisting, or other damage shall be removed before further flight and submitted to Hamilton Standard for repair. A complete description of the circumstances surrounding the incident plus all available alignment records shall accompany the blade, since such details will determine the extent of the repair required.

  (2) Blades with no visual evidence of bending, twisting, or other damage shall be treated as follows:

    (i) If the applicable alignment gage is available, measure alignment and disposition blades in accordance with Hamilton Standard Service Bulletin No. 602A.

    (ii) If an alignment gage is not available, measure propeller track. If track is beyond the tolerance specified in Table II of Hamilton Standard ServiceBulletin No. 596A, the propeller shall be removed from service immediately. If track is within limits, the propeller may be continued in service for a period not to exceed 50 hours' time in service before the face alignment check prescribed in (i) is conducted.

(Hamilton Standard Service Bulletins Nos. 596, 596A, 596B, and 602A cover this same subject.)

This supersedes AD 59-17-03.

This directive effective March 1, 1964.
