N444VR

HISTORY OF FLIGHTOn March 9, 2012, about 1034 eastern standard time, a Cirrus SR22, N444VR, was substantially damaged during a forced landing near Homestead, Florida. The certificated flight instructor, private pilot, and passenger, were not injured. Day visual meteorological conditions prevailed, and an IFR flight plan was filed for the instructional flight conducted under 14 Code of Federal Regulations (CFRs) Part 91, which departed Opa-Locka Executive Airport (OPF), Miami Florida, destined for Key West International Airport (EYW), Key West, Florida.

According to the flight instructor, prior to departure from OPF he had the fuel tanks filled to capacity and he added oil to the engine to bring it up to 5 quarts.

They departed to the east from OPF at approximately 1000, and were given the MIAMI ONE DEPARTURE, MNATE TRANSITION (MIA1.MNATE) then direct to EYW. During the departure they were eventually cleared to 6,000 feet above mean sea level (msl). Once they were leveled off and in the approximate vicinity of Ocean Reef Club Airport (07FA), Key Largo, Florida, the engine incurred a total loss of power. The flight instructor believed however that at the time, the engine was still producing partial power. He then established best glide speed and turned towards 07FA, while the private pilot declared an emergency with Miami Air Traffic Control Center. They "quickly went through the troubleshoot checklist" but could not regain engine power. The airplane was now descending through 4,000 feet msl. The flight instructor then realized that there was a 20 knot headwind, that they were approximately 10 nautical miles from 07FA, and that they were descending at 1,000 feet per minute. He realized that they would not be able to make the airport, so he turned to the left to take advantage of the tailwind and headed for US Highway 1.

He could not recall the exact altitude but as they got lower, he noticed the amount of cars that were on the highway and decided that the risk was too great to attempt to land on it. At approximately 2,000 feet msl, they considered deploying the installed Cirrus Aircraft Parachute System (CAPS) but noticed a light colored patch of ground which appeared to be a hard dirt surface which landing on, seemed to be a better option than deploying the CAPS.

During the final approach while in ground effect the flight instructor then observed a mound of dirt that was directly in front of him and deployed 50 percent wing flaps to "balloon" the airplane over the obstacle. He then heard the stall warning horn, and the wheels touched down on water "like a soft seaplane landing" and slid over a long mound of dirt. The flight instructor then kept the control wheel all the way back and held it till the airplane came to rest in a water filled marshy area. PERSONNEL INFORMATIONAccording to FAA and pilot records, the flight instructor held a commercial pilot certificate with ratings for airplane single-engine land, airplane single-engine sea, airplane multi-engine land, and instrument airplane. His most recent FAA first-class medical certificate was issued on August 7, 2009. He reported 2,100 hours of total flight experience.

The private pilot held a certificate with ratings for airplane single-engine land, and instrument airplane. His most recent FAA third-class medical certificate was issued on July 27, 2009. He reported 480 hours of total flight experience. AIRCRAFT INFORMATIONAccording to FAA and airplane maintenance records, the airplane was manufactured in 2003. The airplane's most recent annual inspection was completed on December 20, 2011. At the time of the inspection, the airplane had accrued 2,888 total hours of operation. METEOROLOGICAL INFORMATIONThe recorded weather at Homestead Air Reserve Base (KHST), Homestead, Florida, approximately 10 nautical miles northwest of the accident site, at 1455, included: wind 110 degrees at 12 knots gusting to 15 knots, visibility 10 miles, sky clear, temperature 26 degrees C, dew point 20 degrees C, and an altimeter setting of 30.20 inches of mercury. AIRPORT INFORMATIONAccording to FAA and airplane maintenance records, the airplane was manufactured in 2003. The airplane's most recent annual inspection was completed on December 20, 2011. At the time of the inspection, the airplane had accrued 2,888 total hours of operation. WRECKAGE AND IMPACT INFORMATIONExamination of the accident site revealed that the airplane had come to rest in mud and water. The bottom of the airplane was immersed to an approximate depth of 9 inches. No fuel residue was present on the water surrounding the airplane.

Landing Gear

Examination of the left and right main landing gear revealed that they had been separated from their mounting locations. The nose landing gear's fairings were torn off but, the nose landing gear strut and wheel assembly was still intact.

Wings

Examination of the left wing revealed that the left wing outboard leading edge was impact damaged, the TKS panel was dented and the leading edge of the upper and lower wing skins, were buckled aft. The wing flap was impact damaged. The fuel cap was closed and secured, and fuel was present to within1 to 2 inches of the top of the fuel tank. Examination of the right wing revealed that the right wingtip was impact damaged, the right navigation light and strobe were impact damaged, and the wing flap was impact damaged. The fuel cap was closed and secured and fuel was present to within 1 to 2 inches of the top of the fuel tank.

Fuselage

Examination of the fuselage revealed that a hairline crack was present along the aft seam cover over the left front CAPS harness attach point on the left side of the fuselage immediately aft of the firewall. Both cabin entry steps were bent aft, and the cowling was impact damaged.

Empennage

Examination of the horizontal stabilizer and elevators revealed no evidence of impact damage, to the horizontal stabilizer. However both elevators were impact damaged and both the left and right tips were bent and torn off. Examination of the rudder and vertical stabilizer revealed no evidence of damage.

Propeller and Engine

Examination of the propeller and engine revealed that the propeller was undamaged. The engine however, had a visible hole in the top of the engine case near the No. 1 and No. 2 cylinders.

Both magnetos were separated from their mounting locations. The left magneto was impact damaged and would not rotate however, internal examination revealed no evidence of any preimpact failure or malfunction. The right magneto would turn freely and the impulse coupling would engage. Bench testing of the right magneto revealed no anomalies and it would produce spark throughout its rpm range. The ignition harness was impact damaged but exhibited normal operating signatures, and the top and bottom sparkplugs exhibited normal wear signatures.

The fuel pump turned freely and no evidence of any abnormalities was present, and it functioned normally through its full range of operation when tested. The throttle, fuel control/ metering assembly functioned normally through its full range of operation when tested. The fuel nozzles were unrestricted and the fuel lines were intact and undamaged. The fuel lines, fuel nozzles, and fuel manifold valve assembly functioned normally through the full range of operation when tested and no leakage was observed from the fuel manifold valve cover vent port during the testing.

The oil sump exhibited minor impact damage. The oil sump drain plug was not safetied. The sump contained 2.5 quarts of oil. The oil was dark in color and contained fragments of engine components. The oil suction screen contained a small amount of debris. The oil filter contained metallic flakes and slivers. The oil pump cavity exhibited scratches but, the oil pump drive was intact, and the oil pump gear teeth exhibited normal operating signatures. The oil pressure relief valve and seat contained no obstructions and exhibited signatures consistent with proper seating. The oil cooler was undamaged.

Cylinder Nos. 1, 4, 5, and 6, exhibited normal operating signatures however, cylinder Nos. 2, and 3, exhibited mechanical damage to their cylinder skirts.

The pistons, piston rings, and piston pins from cylinder Nos. 1, 3, 4, 5, and 6, also exhibited normal operating signatures. The piston skirt, piston rings, and piston pin from cylinder No. 2 however, exhibited mechanical damage.

The crankshaft and counterweight assembly exhibited lubrication distress, thermal damage, and mechanical damage concentrated at the No. 2 connecting rod journal. The No. 2 connecting rod journal also exhibited signs of lubrication distress, thermal discoloration, mechanical damage, and displacement of the journal material.

The No.2 main bearings exhibited contamination imbedded in the surface layer. The bearings exhibited wear consistent with high time engines and the Babbitt layer had been worn through. The bearings were also fragmented and extruded from the bearing support. The bearing had shifted in the main bearing support and the lock slot in the crankcase was damaged indicating that inadequate torque of the crankcase through bolts existed.

The No. 2 connecting rod exhibited extreme thermal and mechanical damage and was fractured through at the base of the I-beam, separating both sections of the bearing supports. Fragments of the connecting rod cap exhibited thermal and mechanical damage. Fragments of the connecting rod bolts and nuts were fragmented through and exhibited mechanical damage and thermal signatures. The piston pin bushing exhibited fractured sections and examination of the No. 3 connecting rod also revealed that it was missing portions of its piston pin bushing. ADDITIONAL INFORMATIONDuring an interview with the flight instructor, he advised that during the preflight he discovered that the oil level was at 3 and ¾ quarts, so prior to departure, he added oil to the engine to bring it up to 5 quarts.
