FAA orders turbocharger valve housing replacement on six BRP-Rotax engine models
The US Federal Aviation Administration has made a mandatory airworthiness directive, a binding safety order, for six variants of BRP-Rotax engines. It was triggered by oil leaking through cracks in a turbocharger valve housing whose wall is too thin. Operators must replace that housing and reidentify the turbocharger.
