# NTSB CHI06CA133: Cirrus Design SR22, N814SN, Verdigre, NE, May 20, 2006 - Type: NTSB accident investigation - Classification: Accident · Serious injuries · Data collection · Final report - Date: May 20, 2006, 10:00 local (15:00 UTC) - Place: Verdigre, NE - Coordinates: 42.673053, -98.226943 - Nearby events: https://openairdocs.org/map.md?lat=42.6731&lon=-98.2269&mi=10 - Phase of flight: [Landing](https://openairdocs.org/ntsb-phases/550) (OpenAirDocs' grouping) - Highest injury: Serious injuries - Injuries: 1 serious, 3 uninjured - Status: Completed, report August 29, 2006 - Report: Approved by Office Director - Parties: Federal Aviation Administration - Lincoln FSDO - NTSB case key (mKey): 63754 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=CHI06CA133 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/63754/pdf - Page: https://openairdocs.org/ntsb/CHI06CA133 ## Probable cause The pilot's decision to land on a wet grass runway that had insufficient length available for landing roll. An additional cause was the pilot's failure to properly retract the flaps during the aborted landing, resulting in diminished climb performance and the collision with the trees. Contributing factors to the accident were that the full length of the runway was not available for landing, the wet grass runway condition, and the trees which the airplane impacted during the aborted landing. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of control - on ground/water, landing - roll - airport facilities,runway/landing area condition - grass (contributing factor) - airport facilities,runway/landing area condition - wet (contributing factor) - In flight collision with object, landing - aborted - aborted landing - performed, pilot in command - all available runway - not available (contributing factor) - performance data - exceeded, pilot in command (cause) - in-flight planning/decision - improper, pilot in command (cause) - altitude/clearance - not obtained/maintained, pilot in command (cause) - flaps - improper use of, pilot in command (cause) - object - tree(s) (contributing factor) - In flight collision with terrain/water, descent - uncontrolled - terrain condition - ground ## Analysis The airplane impacted trees during an aborted landing attempt. The pilot reported that his private grass airstrip was 2,700 feet long and 75 feet wide. The pilot stated that the runway was wet due to a rain shower earlier that morning. The pilot reported that about one-half of the runway had been seeded recently and as a result he attempted to land on the remaining portion of runway. The pilot stated that upon landing the airplane began to slide on the wet runway when he applied brakes. The pilot reported that he initiated an aborted landing, but the airplane impacted two trees after becoming airborne. The trees were positioned about 50 feet past the departure threshold. The landing roll distance for a dry, level, paved runway, was 1,205 feet, according to the Cirrus SR22 Pilot Operating Handbook (POH). The POH indicated that the calculated landing distance should be increased by 40% for operations on grass runways, which resulted in a landing distance of 1,687 feet. The POH did not include an adjustment factor for operations on wet runways. According to a post-accident examination of the runway, the airplane touched down with about 1,265 feet of runway remaining. According to the POH, the flaps should be retracted to 50% during an aborted landing to maximize climb performance. The flaps were found fully extended at the accident site. ## Factual narrative The airplane impacted trees during an aborted landing attempt.
