Sikorsky S6115-20201-1 & -2 Blades.
ABS is the only company with the tooling and expertise to convert
blades from one configuration to another IAW AFC-337. An example of
this is converting the S6115-20201-1/-2 blades to S6115-20201-3
configuration which includes removing the cuff and tip dam seal to be
able to remove, re-configure and re-install the counterweights in the
leading edge of the spar. This change allows for the installation of a
nickel abrasion strip on the blade spar and the tip cap.
Sikorsky S6115-20201-3 blades
ABS repaired 30 each S6115-20201-3 main blades for Clayton Intl., who
ultimately sold the blades to the Canadian DOD for installation on
their Sikorsky Sea King helicopters. About half of the blades were
converted from blades received from the Danish Air Force. These
ex-Danish blades were p/n S6115-20501-009 & -041 civilian short
spar blades. These blades were converted by ABS to the S6115-20201-3
blades that are eligible for installation on the Canadian Sea King.
Sikorsky S6117-30101 Series Tail Blade.
ABS initiated a program for the S-61 tail blade where we replaced the
spar of a S6117-30101 series tail blade that was damaged beyond repair
limits, with a new spar. The blade assembly would then be built up with
all new parts including pocket, abrasion strip & tip cap.
This repair is FAA DER approved.
