## The airworthiness directive

76-11-09 PIPER AIRCRAFT CORPORATION: Amendment 39-2632. Applies to PA-32R-300 airplanes, 32R-7680001 through 32R-7680132, 32R-7680134 through 32R-7680175, 32R-7680177 through 32R-7680200, 32R-7680202 through 32R-7680204 and 32R-7680207, certificated in all categories.

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

To prevent fuel leakage, accomplish the following:

1. For both right and left wings, gain access to the fuel line segment, Piper Part Number 67700-96, through left and right wheel well inboard closeout plates (see sketch below).

2. Inspect fuel lines, Piper Part Number 67700-96, for indication of chafing and/or fuel leakage caused by interference with the close-out plate attachment screws.

a. If a line is damaged, replace with a new fuel line, Piper Part Number 67700-96, or an equivalent part approved by the Chief, Engineering and Manufacturing Branch, Federal Aviation Administration, Southern Region. If necessary, reform Piper Part Number 67700-96 upon installation to provide a minimum of 1/4" clearance with close-out plate attachment screws.

b. If lines are not damaged, hand form, if necessary, to provide a minimum of 1/4" clearance with close-out plate attachment screws.

CAUTION

Parts a and b above, if hand forming of line is necessary, form only enough to insure clearance. Avoid "kinking" or restricting line when forming. Check security of fittings and fuel flow through lines after forming.

Piper Service Bulletin No. 503 also pertains to this same subject.

This amendment becomes effective June 9, 1976.
