## Other investigations on N48K (2)

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.

- [NTSB SEA03LA034](https://openairdocs.org/ntsb/SEA03LA034), Feb 4, 2003: Beech E18S (N48K), Burlington, WA, substantial damage. Probable cause: The pilot's failure to adequately remove ice/frost from the aircraft and to maintain airspeed during the initial climb after takeoff. An inadequate preflight was a factor.
- [NTSB CHI90LA072](https://openairdocs.org/ntsb/CHI90LA072), Jan 25, 1990: Beech E18S (N48K), Oak Creek, WI, substantial damage. Probable cause: IMPROPER PLANNING/DECISION BY THE PILOT.
