Abstract

Air Conditioning (AC) is the one of system in aircraft to make a passanger and all cabin crew comfortable. Trim Air Pressure Regulating and Shutoff Valve or also known as Trim Air PRSOV is a component on the Boeing 737-800 aircraft to regulate flow of hot air constantly before entering the aircraft cabin. Refering to the data for the last 6 years, the replacement of the component belonging to one of the Indonesian national flight carrier using Boeing 737-800 aircraft was the occurance of 84 times the cooling system failure which caused the light indiacator in the cockpit to light up. Among them happened 70 times unscheduled maintenance and 14 times scheduled maintenance. Thus, this essay was made to analyze the causes of the damage that occurred to the Trim Air PRSOV. The method used in this research is Failure Mode and Effect Analysis (FMEA) is the technique used to find, identify and eliminate failures or damage to a system or process. The first step is to analyze using a Pareto diagram and then continue with the FMEA method so that an analysis of the damage that often occurs is damage to the diaphragm with 42% damage with an RPN value of 389.1, erosion on the ring seal with 22% damage with an RPN value of 376 and shaft seal damaged with 12% damage with an RPN value of 295.1 for it requires aggressive treatment. Therefore, repairs with a long TAT of 14 days are expected to increase the reliability of the PRSOV Trim Pressure component. For this reason, repairs are carried out with a long TAT of 14 days, it is hoped that there will be an increase in the reliability of the PRSOV Trim Pressure componen.

Abstract

Aircaft are the most popular means of transportation in the delivery of goods from one area to another. These things can be inaminate objects or living things. Goods transported to the cargo area can be a trigger for damage to the cargo area of the Airbus 330 aircraft, such as spilling fluid from the cargo packaging and the loading process or unloading cargo can cause corrosion in the cargo areaRoller track cargo compartment is one part of the aircraft that is susceptible to corrosion. In aircraft maintenance manual there is no step to apply coating application, where it is known that the coating is one of the protective coatings of a metal to overcome the attack from corrosion. The trial of coating application on the A330-200-200/300 roller track compartment roller track model was conducted for 1670 hours to determine the comparison of roller track corrosion rate values given the av15 adrox protective coating with roller tracks that were not given the av15 adrox protective coating. The test results obtained that the average value of corrosion rate of roller track models with coating coating layers is 0.1505 and without coating layer which is 0.4045 mmpy with coating usage efficiency of 62.7%. So it can be concluded that the application of coating on roller track cargo compartment is effective in inhibiting corrosion rate.

Abstract

Information on weather conditions is needed to support flight safety, especially in the process take-off. One of the required weather information is wind data, wind direction and wind speed. One of the wind components is the tailwind(wind from behind). In the small airports it can only be visited by aircraft such as ATR72 and its kind, due to the limited availability of runways and currently many of these airports are still using landing and take-off in the direction of thewind. This can result in a lack of lift during take-off during the tailwind conditions. To prevent this from happening, there is a reduction in the capacity of the aircraft. The purpose of this study was to analyze the performance of the ATR72 aircraft during take-off with tailwind conditions. By calculating the takeoff under normal conditions on the ATR72 aircraft then varying the tailwind speed. The results obtained are the value of the ground roll distance  (????????) and the reduction in aircraft weight (????) at the time of tailwind. a speed tailwind of 0 or normal, obtained a distance of ground roll 849 m, take-off weight of 20948 kg, reduction in aircraft weight of 0. Speed tailwind of 5 kts, distance of ground roll 773 m, take-off weight of 20333 kg, reduction in aircraft weight of 615 kg, while speed of tailwind 10 kts obtained distance of ground roll 697 m, take-off weight of 19308 kg, reduction in aircraft weight of 1640 kg, and speedtailwind of 15 kts, distance of ground roll 621 m, take-off weight of 18225 kg, was obtained. reduction in aircraft weight by 2723 kg.
