Plain English Summary

3/10 complexity

This Directive requires owners/operators of all Piper PA-22 (Tri‑Pacer and Colt) aircraft to re‑route the fuel primer—and if needed the wheel‑brake hydraulic—lines so they do not pass behind the exhaust muffler, and to clamp them to the firewall per Piper Service Letter No. 213. It must be done within 25 hours TIS to reduce the risk of heat/contact damage and possible in‑flight fire.

Amdt 2

Fuel Primer and Hydraulic Lines - Re-Routing 4/85 DM

Applicability: All models.

Requirement: 1. To prevent contact with the exhaust muffler, re-route fuel primer line, and wheel brake hydraulic line if necessary, to ensure that they do not pass behind the muffler.

Using clamps, secure the lines to the firewall - refer to Piper SL No. 213 for fuel primer line clamping instructions.

Note: FAA AD 53-24-4 refers.

Compliance: Within 25 hours time in service after 31 March 1985.

Background: This Directive has been amended to combine the intent of Piper SL No. 213 and FAA AD 53-24-4 into a single requirement. Re-routing, as applicable, of the fuel primer line and wheel brake hydraulic line is necessary to preclude the possibility of an in- flight fire.
