# NTSB LAX05CA071: Robinson R22B, N1122R, Rialto, CA, January 16, 2005 - Type: NTSB accident investigation - Classification: Accident · No injuries · Data collection · Final report - Date: January 16, 2005, 13:40 local (21:40 UTC) - Place: Rialto, CA - Coordinates: 34.124168, -117.400833 - Nearby events: https://openairdocs.org/map.md?lat=34.1242&lon=-117.4008&mi=10 - Phase of flight: [Landing](https://openairdocs.org/ntsb-phases/550) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 2 uninjured - Status: Completed, report April 28, 2005 - Report: Approved by Office Director - Parties: Federal Aviation Administration - NTSB case key (mKey): 60873 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=LAX05CA071 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/60873/pdf - Page: https://openairdocs.org/ntsb/LAX05CA071 ## Probable cause the student pilot's improper use of the cyclic control during a practice autorotation, and the inadequate supervision by the certified flight instructor. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Miscellaneous/other, landing - flare/touchdown - misc rotorcraft,main rotor/tail boom contact - cut/severed - emergency procedure - simulated - autorotation - performed - cyclic - improper use of, dual student (cause) - supervision - inadequate, pilot in command(cfi) (cause) ## Analysis During a practice full-touchdown autorotation, the main rotor blades struck and severed the tail boom. The certified flight instructor (CFI) said that the purpose of the flight was to prepare the commercial pilot (student) for his CFI check ride and they were performing full touchdown autorotations. The helicopter was aligned with the centerline of the south taxiway. At 60 feet agl, the student flared the helicopter and then leveled it for a full touchdown autorotation. When the helicopter was 1 foot agl, the student pushed the cyclic forward and the forward tips of the skids touched the ground. The helicopter rotated aft, and the CFI assumed the controls and leveled the helicopter. Upon touchdown, the main rotor blades contacted the tail boom. The CFI noted no mechanical malfunctions with the helicopter. ## Factual narrative On January 16, 2005, at 1340 Pacific standard time, a Robinson R22B, N1122R, experienced main rotor contact with the tailboom during a practice full-touchdown autorotation at the Rialto Municipal Airport, Rialto, California. Universal Air Academy was operating the helicopter, registered to a private company, under the provisions of 14 CFR Part 91. The certified flight instructor (CFI) and the commercial pilot-undergoing-instruction (PUI) were not injured; the helicopter sustained substantial damage. The CFI and PUI departed from the El Monte Airport, El Monte, California, about 1300 for the local area instructional flight. Visual meteorological conditions prevailed, and no flight plan had been filed. The CFI submitted National Transportation Safety Board (NTSB) Form 6120.1/2, the Pilot/Operator Report. He said that the purpose of the flight was to prepare the PUI for his CFI checkride, and they were performing full touchdown autorotations. The helicopter was aligned with the centerline of the south taxiway. Approximately 200 feet above ground level (agl), the CFI noted the following performance indications: main rotor rpm "in the green," airspeed 6 knots; and descent rate 1,300 feet per minute. At 60 feet agl, the PUI flared the helicopter and then leveled it for a full touchdown autorotation. When the helicopter was 1 foot agl, the PUI pushed the cyclic forward and the forward tips of the skids touched the ground. The helicopter then rotated aft, and the CFI assumed the controls and leveled the helicopter. Upon touchdown, the main rotor blades contacted the tailboom. The CFI noted no mechanical malfunctions with the helicopter. ## Aircraft - Registration: [N1122R](https://openairdocs.org/deregistered/N1122R-2005-06-16), registration cancelled 2005-06-16, S/N 3197, built 2001 (OpenAirDocs) - Reported make and model: Robinson R22B - Registry model: [Robinson Helicopter R22 BETA](https://openairdocs.org/model/robinson-helicopter-r22-beta) (registry code 7640110) (OpenAirDocs) - Registry engine: [Lycoming O&VO-360 series](https://openairdocs.org/engine/lycoming-o-vo-360-series) (registry code 41514, reciprocating) (OpenAirDocs) - Category: Helicopter - Serial number: 3197 - Engines: Lycoming O-360 reciprocating - Damage: Substantial damage - Flight: Instructional, Part 91 - Operator: Universal Air Academy - Registered owner: Business Financial Services - Airworthiness certificate: Standard, Normal - Departed: EMT, El Monte, CA - Destination: L67, Rialto, CA - Airport: L67, Rialto Muni Airport ## Flight crew As NTSB recorded them.
