## Narrative

As the FAA filed it, in capitals; the FAA replaces private details with ^PRIVACY DATA OMITTED^.

NARRATIVE: THIS REPORT IS IN RESPONSE TO AN FAA FORM 8020-11, INCIDENT NO. ZMP-ARTCC-1412, DATED 07/30/97, RECEIVED FROM THE MINNEAPOLIS ARTC CENTER. THE INCIDENT REPORT STATED THAT ON JULY 29, 1997 AT ABOUT 1210 UTC, N3741MM BEECHCRAFT, E90, WAS AT 16,000 FEET WHEN THE ATC EQUIPMENT INDICATED N3741M, AT 12,000 FEET. N3741M LANDED IN BISMARCK, ND AND A LEAK IN THE AIRCRAFT'S STATIC EQUIPMENT WAS DETECTED. THE PROBLEM WAS CORRECTED BY A LOCAL, BISMARCK, ND CERTIFICATED REPAIR STATION, AND THE AIRCRAFT WAS APPROVED FOR RETURN TO SERVICE ON JULY 29, 1997. AFTER A PRELIMINARY INVESTIGATION OF THE INCIDENT, AIRWORTHINESS IS CONSIDERED A FACTOR IN THE CAUSE OF THE INCIDENT. A LEAK IN THE AIRCRAFT'S STATIC SYSTEM CAUSED AN INVALID ALTITUDE INDICATION. THIS PROBLEM WAS CORRECTED AND THE AIRCRAFT WAS APPROVED FOR RETURN TO SERVICE.

From the FAA Accident/Incident Data System. Reports are matched to registry aircraft by N-number and event date, checked against the reported make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model. For accidents, the NTSB's own investigation is the fuller record.
