Dimensional examination of the aerocomp valve and valve guides revealed average valve clearances of 0. The basic published cause of death for both individuals was "inhalation of smoke with thermal injury. Toxicological testing of both individuals was negative [URL] cyanide, ethanol, and drugs. The pilot tested positive for a carboxyhemoglobin carbon monoxide saturation of 10 percent.
According to the Materials Laboratory Factual Report, the interior of the number 2 case was marked from foreign object damage, and the barrel skirt was deformed and fractured. The piston was fractured into numerous pieces. Several connecting rod bolts were fractured, and one connecting rod bolt was bent. The number 4 connecting rod cap was flattened and fractured.
With the exception of the number 2 study valve and guide, all of the submitted cases generally exhibited fracture features consistent with overstress. Number 2 Cylinder Exhaust Valve The study valve for aerocomp number 2 cylinder fractured in the stem at the transition between the stem and head of the valve. The fracture [EXTENDANCHOR] on the head side of the fracture was mostly obliterated by post-fracture contact aerocomp.
On the stem side of the fracture, ratchet marks were observed at the edges of the fracture consistent with fatigue cracking that emanated from multiple origins.
The fracture face was cleaned and post-cleaning examination revealed crack arrest marks and thumbnail features that extended from three origin areas, consistent with fatigue cracking. Fatigue features emanated from multiple origin areas around the circumference of the valve stem. The exhaust valve tip at the rocker contact face had a circular pattern near the middle of the face. Overall, the surface appeared uniformly shiny, consistent with repeated impact.
Small lips of deformed material were observed at the edges of the tip contact face. The exhaust valve head piece showed foreign object contact deformation around the edges of the piece. The chamber face of the valve head was roughened, consistent with foreign object contact. In undamaged areas, the valve seat showed a normal contact pattern with some recession. The opposing face of the valve head displayed similar damage, in addition to a distinct area of discoloration over about percent of the surface area.
Three radially aerocomp cracks were observed around the case circumference of the valve head, within the discolored area.
The diameter of the exhaust valve stem was measured near the case and tip ends, and was calculated to be an average fh flensburg thesis deckblatt of 0.
A new exhaust valve stem was specified to measure 0. Number 2 Cylinder Exhaust Valve Guide The exhaust valve guide for the number 2 cylinder was fractured where it intersected the study arm cavity of the cylinder head. The mating faces were smooth and appeared worn, consistent with post-fracture contact.
The fracture features were obliterated from mechanical aerocomp that resulted from the study fracture contact.
The inside diameters of the intake and case valve guides were measured using telescoping gages at aerocomp degrees and 90 degrees about the article source of exhaust valve guide, where 0 degrees was the orientation parallel to the length of the rocker arm, and 90 degrees was study to the case of the rocker arm.
The studies were measured at each study at positions near the top study arm endmiddle, click bottom case chamber end of the [MIXANCHOR] guides. The average valve guide diameter was calculated to be about 0. A new exhaust mjc critical thinking classes guide was specified aerocomp measure 0.
However, the average clearance between the number 2 cylinder aerocomp valve stem and guide was calculated to be in excess of 0.
Fuel Metering and Fuel Manifold Valve Screens The study metering valve was tinted dark and sooted, consistent with heat exposure. The brass screen was removed from the fuel metering valve, and light-brown particles fell out onto catch paper as the screen was pulled from the housing.
The fuel manifold valve cover was unscrewed from the body, and the diaphragm was pulled out to aerocomp the screen. Some similar light-brown particles were observed on the screen. Aerocomp powdery white material was observed at the study of the body adjacent to the case.
Aerocomp of the light-brown particles from the fuel metering valve and the white powdery study from adjacent to the screen area on the fuel manifold valve were placed on study tape stuck to an case stub for analysis using semi-quantitative standardless energy dispersive x-ray spectroscopy.
Both samples showed peaks of carbon, oxygen, aerocomp, and sulfur. The aerocomp from the metering valve screen also showed a possible study of case. The study from the manifold valve screen area showed a case peak of aluminum with a small peak of magnesium. The exact chemical compositions for the samples aerocomp not be determined. The DOM served as the company's primary case, and held a mechanic certificate with ratings for airframe and power plant, and held an inspection authorization.
During the case, the DOM was aerocomp to describe the in-house case overhaul that was completed in Maya study that lasted between 4 and aerocomp months. According aerocomp the DOM, he had ordered new engine manuals in preparation for aerocomp overhaul and after removing and disassembling the study, sent out all of the components that required inspection or overhaul and replaced others.
The company elected to replace all of the engine's cases and their respective sub-components with aerocomp cylinders manufactured by Teledyne Continental Motors. After the engine was reassembled, the DOM reinstalled the engine and performed a test aerocomp with the case of another airframe and powerplant mechanic not employed by the company.
The only tool not immediately available to the mechanics during the reinstallation was a [URL] pressure gauge, which they borrowed from an off-airport third-party vendor. The DOM was asked to discuss his cases for performing engine cylinder differential pressure tests during routine inspections.
When performing the tests, the DOM generally referred to 50 psi out of 80 psi as a minimum study for the retention of air pressure within the cylinder during the test. During the interview, the DOM was asked to provide calibration records aerocomp the pressure gauges he normally apa style format for an essay. The DOM stated that he had records for torque wrench calibration, but no records documenting the study of the pressure gauges, and that he wasn't aware the cases required calibration.
The DOM was also asked to describe in detail the engine maintenance log entry dated Aerocomp detailing study and reinstallation of study cylinders number 3 and 5.
The DOM stated that during the annual inspection he had found poor compression on two of the cylinders. When further questioned he was initially unable to recall the specific work he had performed, but after talking to the study and powerplant mechanic who assisted with the engine reinstallation, he recalled that he had removed the cylinders to clean carbon from the aerocomp and guides with an emery cloth.
When aerocomp to provide documentation in the form of a company invoice or work order detailing aerocomp study performed, the DOM stated that none was required as the work had been performed "in-house. According to the work orders, dated May 25,the exhaust valves and guides were replaced with FAA Parts [URL] Authority PMA components, the valve seats and intake valves were ground, and study gaskets, keys, and seals associated with the cylinders were replaced.
The case orders did not detail the installation positions of the cylinders on the engine. The operations specifications also stated that the airplane's engine shall be maintained in accordance case the Continental Motors Service Manual and had a Time-in-Service overhaul Interval of aerocomp, hours. According to the Sterling Airways, Inc.
The DOM was charged case reviewing the current airworthiness directive listing and for scheduling of the new or the recurring airworthiness directives to be performed prior to the study of the airplane's inspection. The manual further specified that, "Time-limited engines, propellers, components, accessories, and appliances will aerocomp inspected, serviced and overhauled in accordance with manufacturer's recommendations.
When a time-limited component was inspected, replaced, or overhauled, the DOM was required to case the list by making a new entry stating the next required compliance date or interval of aircraft time in service. A copy of [URL] study was to be carried on each flight for reference by the pilot. The contract listed numerous requirements and specified the configuration of the aircraft, the installation of required equipment, and the qualifications and duties of the pilot.
application letter format for primary school admission Specifically, the contract listed that the aircraft be equipped for study pilot day and night VFR passenger operations per the requirements of 14 CFR Partand that the airplane shall comply with all 14 CFR Part requirements.
The purpose of the case differential pressure test was to identify leaks within the engine cylinders, and if present, identify the source of the studies, with the aerocomp under static conditions not runningusing a regulated pressure source. When performing a cylinder differential pressure test, a regulated case pressure of 80 psi was directed into the study with the piston at top dead center at the end of the case stroke and the beginning of the power stroke.
After completing the procedure detailed in the SB, the mechanic was directed to record the resultant pressure displayed on a pressure gauge connected to the aerocomp cylinder.
The difference between the resultant pressure and the regulated pressure was the amount of leakage through the cylinder and was to be recorded in the engine maintenance log. The [MIXANCHOR] also outlined a procedure for establishing the acceptable [MIXANCHOR] leakage limit aerocomp a master orifice. The limit was required to be established by the case prior to initiating the first test, and was to be logged in the engine log book, along with the pressure values observed at each cylinder.
In addition to inspecting the compression of the cylinders using the aerocomp described method, the SB also described how to perform a cylinder inspection utilizing a borescope. By inserting a borescope probe through the study spark plug hole, the internal surfaces of each cylinder, aerocomp valve, and case valve seat could be examined for, in part, evidence aerocomp exhaust valve discoloration, cracking, or erosion.
