(-23) AIRCRAFT HAD AN ELECTRICAL FAILURE RESULTING IN A PARTIAL LANDING GEAR EXTENSION, DAMAGE WAS LIMITED TO WINGTIP AND SKIN. INVESTIGATION INTO THE CAUSE OF THE ELECTRICAL FAILURE CONTINUES. FINDINGS WILL BE REPORTED VIA AN AMENDMENT TO THIS REPORT. (.19) ON JULY 16, 1999, AT 1100 MOUNTAIN DAYLIGHT TIME, A CESSNA T210M, N6029N, SUSTAINED SUBSTANTIAL DAMAGE DURING A PARTIAL LANDING GEAR RETRACTED LANDING AT CEDAR CITY, UTAH. THE PRIVATE PILOT AND HIS PASSENGER WERE NOT INJURED. VISUAL METEOROLOGICAL CONDITIONS PREVAILED FOR THIS PERSONAL CROSS-COUNTRY FLIGHT OPERATING UNDER TITLE 14 CFR PART 91 AND NO FLIGHT PLAN WAS FILED. THE FLIGHT DEPARTED SALT LAKE CITY, UTAH AT 0930, WITH AN INTENDED DESTINATION OF SAINT GEORGE, UTAH. ACCORDING TO INFORMATION PROVIDED BY THE PILOT, THE FLIGHT WAS OVER FLYING CEDAR CITY WHEN ALL ELECTRICAL POWER WAS LOST DUE TO AN ALTERNATOR FAILURE. THE PILOTS' ATTEMPTS TO LOWER THE LANDING GEAR VIA THE ALTERNATE METHOD RESULTED IN THE NOSE LANDING GEAR BEING EXTENDED AND THE MAIN LANDING GEAR REMAINING IN THE RETRACTED POSITION. DURING THE ENSUING EMERGENCY LANDING, DAMAGE WAS INCURRED WHICH NECESSITATED REPLACEMENT OF A HORIZONTAL STABILIZER AND ELE VATOR. (.4) ON JULY 16, 1999, AT 1100 MOUNTAIN DAYLIGHT TIME, A CESSNA T210M, N6029N, SUSTAINED SUBSTANTIAL DAMAGE DURING A PARTIAL LANDING GEAR RETRACTED LANDING AT CEDAR CITY, UTAH. THE PRIVATE PILOT AND HIS PASSENGER WERE NOT INJURED. VISUAL METEOROLOGICAL CONDITIONS PREVAILED FOR THIS PERSONAL CROSS-COUNTRY FLIGHT OPERATING UNDER TITLE 14 CFR PART 91 AND NO FLIGHT PLAN WAS FILED. THE FLIGHT DEPARTED SALT LAKE CITY, UTAH AT 0930, WITH AN INTENDED DESTINATION OF SAINT GEORGE, UTAH. ACCORDING TO INFORMATION PROVIDED BY THE PILOT, THE FLIGHT WAS OVER FLYING CEDAR CITY WHEN ALL ELECTRICAL POWER WAS LOST DUE TO AN ALTERNATOR FAILURE. THE PILOTS' ATTEMPTS TO LOWER THE LANDING GEAR VIA THE ALTERNATE METHOD RESULTED IN THE NOSE LANDING GEAR BEING EXTENDED AND THE MAIN LANDING GEAR REMAINING IN THE RETRACTED POSITION. DURING THE ENSUING EMERGENCY LANDING, DAMAGE WAS INCURRED WHICH NECESSITATED REPLACEMENT OF THE HORIZONTAL STABILIZERS AND ELEVATORS. ACCORDING TO A MECHANIC WHO EXAMINED THE AIRCRAFT, THE ELECTRICAL FAILURE WAS DUE TO A FAULT IN THE ALTERNATOR. THE MECHANIC PROVIDED AN OPINION THAT A CHECK VALVE IN THE LAN DING GEAR HYDRAULIC SYSTEM MAY NOT HAVE OPERATED PROPERLY AND THIS COULD HAVE PREVENTED ALTERNATE LOWERING OF THE MAIN LANDING GEAR. PROCEDURES IN THE AIRPLANE OPERATING MANUAL (APPLICABLE PAGES ATTACHED), STATED THAT "IF THE LANDING GEAR FAILS TO EXTEND VIA THE ALTERNATE METHOD ELECTRICAL POWER SHOULD BE TURNED OFF BY SECURING THE AVIONICS POWER AND MASTER SWITCHES AND ANOTHER ATTEMPT SHOULD BE MADE. AFTER EXTENSION, THE SWITCHES SHOULD BE TURNED BACK ON TO VERIFY LANDING GEAR POSITION." BASED ON A TELEPHONE INTERVIEW WITH THE PILOT AND INFORMATION PROVIDED IN WRITING, THE PILOT DID NOT FOLLOW THESE PROCEDURES. ## The NTSB's investigation of this event (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 DEN00LA033](https://openairdocs.org/ntsb/DEN00LA033), Jul 16, 1999: Cessna T210M (N6029N), Cedar City, UT, substantial damage. Probable cause: The pilot's failure to follow alternate landing gear extension procedures. Factors were the main landing gear failure to extend and a loss of electrical power. 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. --- OpenAirDocs.org is an independent research project of [Contrail Labs](https://contraillabs.com/).
