Re: 5 Dead In MO SR-22 Chrash
I absolutely agree that speculation is worthwhile. But I was unable to see what was to be learned from your speculation because it seemed to me to provide at least two (or three?) possible causes. I also I don't know what you meant by "Improper IFR". Flying VFR into IMC?
I disagree with your assertion that we have all the information that an investigator is likely to have. The one person I personally knew who died in an aviation accident turned out to have THC in his blood, indicating use of marijuana within 3 hours of the accident. The NTSB listed it as a contributing factor.
We also don't have the radar tracks and any ATC communications. If he was IFR then his dealings with ATC might add insight. The
video story on this web page includes an interview with witnesses who claimed to have thought the airplane sounded like it might have had problems prior to impact.
If it turned out the pilot knew there was a problem, then why didn't he deploy the parachute? That is the frustrating aspect to me.
Well here you go Jim. Emphasis mine. You may find a definition of "improper IFR in an aviation safety article written by yours truly (~2003 IIRC, copy not on this computer), and at the NTSB site simply by using "improper IFR" in the text search box.
NTSB Identification: CEN12FA633
14 CFR Part 91: General Aviation
Accident occurred Saturday, September 15, 2012 in Willard, MO
Aircraft: CIRRUS DESIGN CORP SR22, registration: N436KS
Injuries: 5 Fatal.
This is preliminary information, subject to change, and may contain errors. Any errors in this report will be corrected when the final report has been completed. NTSB investigators either traveled in support of this investigation or conducted a significant amount of investigative work without any travel, and used data obtained from various sources to prepare this aircraft accident report.
On September 15, 2012, about 0023 central daylight time, a Cirrus Design SR22, N436KS, was substantially damaged when it impacted terrain near Willard, Missouri. The pilot and four passengers were fatally injured. The aircraft was registered to and operated by JL2, LLC under the provisions of 14 Code of Federal Regulations Part 91 as a personal flight. Instrument meteorological conditions prevailed for the flight, which was operated on an instrument flight rules flight plan. The flight originated from Lee’s Summit Municipal Airport (LXT) about 2340 on September 14, 2012. The intended destination was the Springfield-Branson National Airport (SGF), Springfield, Missouri.
Springfield Approach was providing air traffic control services to the flight at the time of the accident. The pilot contacted Springfield Approach about 0002 as the flight entered their airspace. About 0017, the pilot was cleared for an Instrument Landing System (ILS) approach to runway 14 at SGF. The pilot was instructed to contact the control tower at that time. At 0020, about 3 minutes after establishing contact with the control tower, the pilot requested radar vectors in order to execute a second ILS approach. About 30 seconds later, radar contact was lost. The controller’s attempts to contact the flight were not successful.
The accident site was located in a pasture about 6 miles northwest of SGF. Ground impact was located in an open area of the lightly wooded pasture field. The airplane was fragmented. The main impact crater contained the propeller, engine, instrument panel, and portions of the fuselage. Linear ground impact marks, consistent with being formed by the wings, emanated from the main impact crater.
Based on the ground impact markings, the airplane was oriented on an approximate heading of 340 degrees at the time of impact. The debris field extended to approximately 110 feet east of the main impact crater. Located within the debris field were the airplane flight control surfaces and wing flaps.
