The airworthiness directive
62-05-02 BRANTLY: Amdt. 402 Part 507 Federal Register February 28, 1962. Applies to All Model B-2 Helicopters With Serial Numbers Prior to 180.
Compliance required within the next 25 hours' time in service after the effective date of this directive.
To preclude failure of the seals in the engine driven fuel pump due to excessively high temperature conditions in the engine compartment, modify the engine driven fuel pump, Lear- Romec Model RD7790D3, to incorporate high temperature seals in accordance with Brantly Service Bulletin No. 16 and Lear-Romec Service Bulletin No. 3.
Reidentify modified units by revising the pump nameplate as follows:
(a) Add suffix "-3" to the pump serial number.
(b) Change pump model number to "RG7790G".
(Brantly Service Bulletin No. 16 and Lear-Romec Service Bulletin No. 3 both cover this same subject.)
This directive effective February 28, 1962.
