## The airworthiness directive

63-02-01 BOEING: Amdt. 527 Part 507 Federal Register January 11, 1963. Applies to All 707/720 Series Aircraft.

Compliance required within the next 500 hours' time in service, unless already accomplished.

The upper and lower fairings installed over the anticollision lights have been found to disturb the light distribution in certain peripheral areas. To prevent a reduction in the effective light intensity:

  (a) Remove the anticollision light upper fairing, (P/N's 69-10789, 9-66041-3000) and the lower fairing, (P/N's 69-10789-1, 9-66041 or 9-66041-3000); and

  (b) Plug the mounting holes for the fairing assembly fasteners with Boeing material specification 5-13 Type A aerodynamic smoother or equivalent.

(Boeing Service Bulletin No. 1651 covers the same subject.)

This directive effective February 12, 1963.
