## Other investigations on N5546Z (1)

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 ATL04LA183](https://openairdocs.org/ntsb/ATL04LA183), Sep 12, 2004: Piper PA-18 (N5546Z), San Juan, PR, substantial damage. Probable cause: The pilot's failure to apply carburetor heat which resulted in carburetor ice and the subsequent loss of engine power. A factor was weather conditions favorable for carburetor ice.
