LIMITATION, CHANGE OF
HELICOPTERS AFFECTED:| Serial numbers 65011 through 65134.

DESCRIPTION
Following engineering analysis to add additional approved fuel types to the
Model 505 type certificate, a discrepancy in an original report was noted. The
re-evaluation of the subject findings demonstrated that for wide cut fuels
such as Jet B and JP-4, the present altitude limitations published was set at
too high of an altitude.
This Alert Service Bulletin (ASB) introduces a change to the Rotorcraft Flight
Manual (RFM) Section 1, Figure 1-6. This change to the limitations section is
introduced in conjunction with the release of BHT-505-FM-1 Rev.3.
Revision A of this bulletin is to supersede this ASB to the ASB 505-22-28 that
mandates the insertion of Figure 1-6 introduced at Revision 5 of the
BHT-505-FM-1 Rotorcraft Flight Manual (RFM). The Revision 5 of the RFM
introduced more stringent limitations
to Figure 1-6 for starting at certain altitudes, ambient temperatures, and
fuel specifications.
APPROVAL
The engineering design aspects of this bulletin are Transport Canada Civil Aviation (TCCA) approved.
