Mass bizjet retirements predicted over ADS-B Out

Engine Assurance Programme (EAP), the Dallas-based maintenance specialist, delivered a dire warning of forced corporate jet retirements caused by a ‘double whammy’ of factors. The US Federal Aviation Administration (FAA) requires aircraft flying above 10,000ft to be equipped with Automatic Dependent Surveillance-Broadcast (ADS-B) Out equipment by 1 January 2020. In addition, replacement of the LPT1 rotor assembly in TFE731-4 and -5 aircraft engines is required under Airworthiness Directive (AD) 2012-17-05 by October 2020. This AD will affect a slew of older models including the Hawker 800/XP, Dassault Falcon 20-5 and early-model Falcon 900, and the Cessna Citation VII. EAP estimates that these requirements will force at least 20% of the older airframes out of service, due to the prohibitive expenses of carrying out the required installations.
