A US Navy shrouded propeller's exte

[boo1]

A US Navy shrouded propeller's exterior paint scheme includes a 3" red strip at the path of blade rotation. MIL-STD-2161A, PAINT SCHEMES AND EXTERIOR MARKINGS FOR U.S. NAVY AND MARINE CORPS AIRCRAFT lists fuselage painting requirements Para 5.5.5.10.3.6. Is this Mil-Std appropriate for the shroud painting requirement? Is this a safety issue?

The stripe You noted is generally placed on the exterior of nacelles, cowls or fuselages (or interiors of military acft fuselages with external props). The stripe is in-line with high speed rotating blade systems and demnotes the likely path of fragments, should an uncontained blade failure occur. It is NOT a good place to be [near] during an engine failure, crash, etc... especially for "people", hazzardous materials/cargo [fuel tanks, other flammable/explosive items, etc], or high-value materials.

If there is any tech-data requirement for such a stripe, put it on... it is a safety issue. Regards, Wil Taylor
