PMV Engineering certified new Bose® A30 Boomsets on ATR, A330, A300-600 aircraft.
To allow usage of this noise-canceling headsets, this modification deals with replacement of the existing Jack Panels and Boomsets by new ones on aircraft.
Noise reduction function is provided through the addition of a 28VDC power supply to each Jack Panel.
ETSO/TSO can be necessary to check performances but is not sufficient to certify installation and the use of boomset by crew. From an airworthiness perspective, boomset is involved in compliance demonstration with CS25 - 25.1457 and AIR-OPS (AMC1 CAT.IDE.A.325 and CAT.IDE.A.185) requirements.
Certification process included a torough verification that the use of Bose A30 headset does not attenuate any aural warnings or sounds necessary for alerting the flight crew on matters related to the safe operation of the aeroplane. Absence of negative impact on CVR recording has also been assessed.
