Peregrine received FAA approval for improved reliability of the Hawker 4000 cooling blowers. Applicable to the entire fleet of the Hawker 4000, formerly known as the Hawker Horizon, the installation data and Supplemental Type Certificates (STCs) #ST01035DE are now available from Peregrine.
The STC and Parts Manufacturing Approval (PMA)-qualified installation hardware improves dispatch reliability and reduces maintenance actions caused by annunciated failures of the aft compartment heat exchange blower. Used during ground operations in higher ambient temperatures, the Peregrine STC incorporates an AMETEK brushless blower exhibiting significantly higher reliability and greater assurance of eliminating hot spots in this compartment.
