The airworthiness directive

55-15-02 CONVAIR: Applies to All 240 and 340 Series Aircraft Equipped with Hamilton Standard Propellers. Compliance required by first scheduled engine change after November 1, 1955, but not later than November 1, 1956.

To increase the fire resistance integrity of the propeller feathering system against damage by a powerplant fire, all flexible hose components of propeller feathering lines forward of the firewall in zone 2 must be replaced with lines and fittings which will meet current fire resistance requirements. Convair Service AirGram No. 123 dated October 8, 1954, covers this subject. The following hose assemblies may also be considered acceptable for this application:

(a) Aeroquip 680-10S hose assemblies with Aeroquip 304 protective sleeves over end fittings (Aeroquip assembly P/N 304000).

(b) Resistoflex-SSFR-3800-10 hose assemblies.
