The airworthiness directive

48-14-04 DOUGLAS: Applies to All C-54 Series Aircraft Prior to Model C-54G.

Compliance required by November 1, 1948.

Because of fire hazard install a tailpipe shroud deflector on each tailpipe shroud assembly to prevent flame from a zone 1 fire entering the engine accessory section through the space existing between the shroud and cowling. AN 3-3A bolts may be substituted for the AN 3C-3A bolts called out in the Service Bulletin.

(Douglas Service Bulletin C-54-289 addendum covers this same subject.)
