ROBINSON HELICOPTER COMPANY, INC.
LIMITED AIRCRAFT WARRANTY
Effective R66 Serial Number 0003 & on
Robinson Helicopter Company, Inc. (hereafter referred to as RHC) warrants each new
helicopter to be free from defects in material and workmanship appearing within two years
from the date of delivery from the RHC factory or during the rst one thousand (1000) hours
of operation, whichever event occurs rst; provided, the aircraft has been subjected to nor-
mal use and service. This Warranty is limited to repair or replacement on an exchange basis,
as selected by RHC, of any part, which upon examination by RHC is deemed to have been de-
fective when the aircraft left the factory. A new warranty period is not established for parts
replaced under the terms of this Warranty. Such replacement parts are warranted only for
the remainder of the original warranty period. This Warranty shall not apply to any helicopter
or part which has been repaired or altered outside the factory, and which, in RHC’s judgment,
has affected the performance or reliability of the helicopter or part. This Warranty shall not
apply to any helicopter or part which has been subject to corrosion, misuse, negligence or
accident, nor to any parts normally replaced during routine maintenance, such as, air
cleaners, skid shoes, rod end or spherical bearings, light bulbs, etc. This Warranty shall not
apply to any helicopter which has been crated for shipping unless such crating is performed
by RHC. RHC is not responsible for the cost of shipping parts under the terms of this
Warranty. However, RHC will credit the RHC Dealership, which sold and delivered the new
helicopter to its original owner, with an allowance for labor performed by that Dealership for
removing and reinstalling the defective part. No credit will be issued for trouble-shooting.
RHC makes no Warranty with respect to batteries, instruments, avionics or other trade
accessories since they are usually warranted separately by their respective manufacturers.
New aircraft are equipped with new engines which have a separate Rolls Royce limited
warranty.
ADDITIONAL WARRANTY FOR MAIN & TAIL GEARBOXES
In addition to the warranty specied above, an extended pro-rated warranty shall apply to the
main and tail gearboxes for the rst 2000 hours of service or three years from the date
of manufacture, whichever event occurs rst. During this period, if a gearbox must be
overhauled due to failure of a part which was defective when it left the factory, RHC will pro-
rate the cost of the overhaul by dividing the hours in service by 2000 or the months in service
by thirty-six (36), whichever fraction is greater.
THE FOREGOING WARRANTY IS EXCLUSIVE AND IS GIVEN AND ACCEPTED IN LIEU OF
ANY AND ALL OTHER WARRANTIES AND REPRESENTATIONS, EXPRESS, IMPLIED, OR
STATUTORY, WHETHER WRITTEN OR ORAL, INCLUDING WITHOUT LIMITATION ANY
IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR
PURPOSE OR TRADE USAGE, THE REMEDIES OF THE BUYER SHALL BE LIMITED TO
THOSE PROVIDED HEREIN. IN NO EVENT WILL THE MANUFACTURER BE LIABLE FOR
LOSSES RESULTING FROM LOSS OF USE OF THE HELICOPTER, COLLATERAL,
CONSEQUENTIAL OR SPECIAL DAMAGES, OR ANY OTHER COSTS.
Warranty adjustments with respect to any helicopter or parts manufactured by RHC will be
made only upon compliance with the following procedure:
(1) The defective part or assembly, together with a written Warranty Claim, must be
returned to RHC not later than thirty (30) days after discovery of the defect nor
more than thirty (30) days after expiration of the Warranty period.
(2) RHC will, after inspection, determine whether the material or part was defective
when it left the factory and will respond accordingly. Final determination of a
Warranty adjustment rests with RHC.
