Circumstances:
The airplane's right engine experienced a complete loss of power immediately after takeoff and the airplane began to slow. The airplane reached an altitude of approximately 91 feet above ground level and then entered an uncontrolled descent consistent with the onset of a velocity minimum control (VMC) roll to the right. No evidence of any preimpact failures or malfunctions with either the engine or airframe was discovered, and evidence at the scene indicated that the landing gear had been retracted and the right engine propeller feathered. Examination of the cockpit revealed the right engine fuel selector was positioned between the "60 GAL RIGHT AUX" detent and the "RIGHT ENG OFF" detent. Examination of the fuel system between the selector and the right engine indicated that it was in this position prior to impact. Also, placards next to the fuel selectors stated, "WARNING POSITION SELECTORS IN DETENTS ONLY. NO FUEL FLOW TO ENGINES BETWEEN DETENTS." The pilot loaded the majority of the cargo and performed the weight and balance calculations. Examination of the fuselage revealed that all six cargo bins were full. The investigation also discovered that the furthest aft bin contained 265 pounds of cargo even though placarded for a maximum of 75 pounds. All other bins were loaded considerably below their maximum weight limits. Weight and balance calculations revealed the information listed on the weight and balance form produced by the pilot was erroneous and that the actual center of gravity (CG) of the airplane was rear of the aft CG limit, which would have created instability in the handling characteristics of the airplane, especially after a loss of engine power. In addition, the aft-of-limit CG would have increased the airspeed needed to prevent the airplane from entering a VMC roll. Performance calculations indicate that with the right engine having lost power immediately after takeoff, the airplane would most likely not have been able to continue the departure on one operating engine.
Probable cause:
A total loss of engine power due to fuel starvation as a result of the pilot's failure to place the fuel selector for the right engine in the proper position. Contributing to the accident was the improper loading of the cargo.

Circumstances:
Prior to the flight, the pilot obtained a weather briefing which included an AIRMET for IFR conditions and an AIRMET for icing that was "just off to the north." According to air traffic control (ATC) information, the en route portion of the flight was uneventful. ATC cleared the pilot for an ILS approach to runway 35, and the pilot acknowledged the approach clearance. When the airplane reached the outer marker ATC approved the pilot for a frequency change to the common traffic advisory frequency. The pilot acknowledged the frequency change, and no further communications were received from the pilot by ATC. Witnesses observed the airplane approximately 200 feet above ground level (agl) on a northwesterly heading, west of runway 35. The airplane then entered a climbing left turn to the south and disappeared into the overcast cloud layer. Shortly thereafter, the witness observed the airplane in a "20 degree nose down, wings level attitude" on a southeasterly heading. The witness then lost sight of the airplane due to hangars obstructing his view. At the time of the accident, the witness stated that the ceiling was approximately 500 foot overcast with mist. The published missed approach procedure instructed the pilot to initiate a climbing left turn to a fix and hold. Examination of the accident site revealed the airplane impacted the terrain in a right wing, nose-low attitude. No ground impact marks were noted except in the immediate vicinity of the wing leading edges, engines, and propeller assemblies. The flaps and landing gear were in the extended position. The leading edge surfaces of the vertical and horizontal stabilizers revealed 1/4 to 1/2 inches of clear ice. The upper fuselage antenna displayed 1/4 to 1/2 inches of clear ice. Local authorities reported observing a "layer of ice" on the leading edges of both wings when they arrived to the accident site. Examination of the airframe and engines revealed no anomalies that would have precluded normal operations.
Probable cause:
The pilot's failure to maintain aircraft control during the missed approach which resulted in an inadvertent stall and impact with terrain. A contributing factor was the icing conditions.

Circumstances:
A witness reported hearing the distinctive sound of a radial engine just before the crash, and right after that a loud crashing noise. The witness observed a large cloud of dust forming, subsequently saw the plane parts scattering from west to east across the pasture, and then observed the fuselage come to rest. A second witness saw the airplane hit the ground and a cloud of dust form about one-quarter of a mile long and as high as a highline wire. The witness said that after the dust settled he saw scattered plane parts, a highline wire down, and a wing part spilling fuel. The witness also stated that the airplane was traveling from west to east and looked horizontal at impact At 12:59:57, approximately 10 minutes prior to the time of the accident, air traffic control radar identified a target 8 nautical miles northwest of the accident site at an altitude of 5,500 feet mean sea level (MSL). However, this target could not be positively identified as the accident airplane. A postmortem examination of the pilot by a Medical Investigator reported significant natural disease findings included coronary atherosclerosis (hardening and narrowing of the arteries), and chronic thyroiditis (inflammation of the thyroid gland). Both of these diseases can cause sudden cardiac problems including an arrhythmia or heart attack.
Probable cause:
The failure of the pilot to maintain clearance.

Crash of a Beechcraft H18 off Manila

Circumstances:
The twin engine aircraft departed Taytay-Sandoval-Cesar Lim Rodriguez Airport on a charter flight to Manila, carrying one passenger and two pilots. While approaching Manila, the left engine failed. The crew informed ATC about his situation and continued the descent to Manila when, shortly later, the right engine lost power. Unable to maintain the assigned altitude, the crew attempted to ditch the aircraft in the bay of Manila, about 3 km offshore. The aircraft floated for few minutes, allowing all three occupants to evacuate the cabin. Few minutes later, the aircraft sank and all three occupants were rescued. The wreckage was not recovered.
Probable cause:
It was reported that white smoke was coming out from the left engine during the descent, forcing the crew to shut it down and feathering its propeller. Due to lack of evidences because the wreckage was not found, the exact cause of the engine failure could not be determined.
