Am i missing something , I did text search for oil and dry and found no reference in this document. Is there a later release ?.
Sorry I found it , after reading back through the thread.
1) Category A. Unless such failures
are extremely remote, it must be
shown by test that any failure which
results in loss of lubricant in any normal
use lubrication system will not
prevent continued safe operation, although
not necessarily without damage,
at a torque and rotational speed
prescribed by the applicant for continued
flight, for at least 30 minutes after
perception by the flightcrew of the lubrication
system failure or loss of lubricant.
(2) Category B. The requirements of
Category A apply except that the rotor
drive system need only be capable of
operating under autorotative conditions
for at least 15 minutes.
And earlier in part 29.1
(c) Rotorcraft with a maximum
weight greater than 20,000 pounds and
10 or more passenger seats must be
type certificated as Category A rotorcraft.
Should this exception have been referenced on the TCDS ?.
