Accident or incident history

We don't import NTSB accident data, so this profile can't say whether N421MD has an accident or incident record. Search the tail number in NTSB CAROL, including any earlier N-numbers the aircraft carried. Open NTSB CAROL.

Airworthiness Directives

We don't import the FAA AD library, so this profile lists no ADs. Which ADs apply to N421MD depends on its airframe, engine, propeller, installed equipment and serial ranges — search each in the FAA AD library (DRS) and check the logbook AD record with your A&P.

Type certificate

CESSNA 421C is governed by the FAA Type Certificate Data Sheet for the CESSNA family. The TCDS is the authoritative reference for engine, weight, and equipment configuration.
