Piston Engine Restrictions

Any finite life or restrictions will, usually, only be imposed by the Manufacturer (OEM). They are usually listed in Chap. 4 of the Maintenance Manual but sometimes in Service Letters, again published by the OEM - of Engine or Airframe.

Any restrictions imposed by the Airworthiness Authority will usually be promulgated in the form of an Airworthiness Directive (AD)
