Managing Aircraft Maintenance Projects Successfully Research Proposal

Managing Aircraft Maintenance Projects Successfully - Research Proposal Example Regulations and common sense both mandate that each aircraft be the subject of a fully documented maintenance protocol towards ensuring the airworthiness and serviceability of the aircraft. Routine preventive maintenance, although well within the purview of common sense, is not a required part of the maintenance protocol. Within the aircraft maintenance protocol, each aircraft and the work required for its service is regarded as an individual project. The reality of aircraft maintenance project management (AMPM) is that several overlapping projects must be managed simultaneously. This presents major obstacles and difficulties for the aircraft maintenance organization in terms of resource management and utilization, budgetary constraints, priority conflicts and lead-time fulfillment. These considerations are compounded by several factors. Greater demands are being placed on aircraft as the number of passenger miles being flown trends upward over time. The number of aircraft being flown also trends upward but at a disproportionate rate. More importantly for the proposed research, the number of aviation maintenance technicians in the industry trends upward at a much lower rate, suggesting that the workload placed on maintenance technicians per capita is becoming ever greater. Air Transport Association o f America statistics for the 12-year period from 1983 to 1995 gives these increases as 187%, 70% and 27% respectively, supporting the ‘work overload’ factor of AMPM. Baron (2009) discusses at some length untoward events that can be attributed directly to the effects of fatigue experienced by aircraft maintenance personnel, and so to the project management practices of their working environments. It is important to note the finding recounted by Baron from a study conducted by Johnson et al in 2002. Based on quantitative and qualitative data, those authors discerned that in general, AMTs and AMEs working in aircraft maintenance services were

Blood component therapy - Assignment Example It has been observed that there is a disorganized practice to place the orders for blood requirement in elective surgeries moreover incidence show a wasteful use of blood in the execution of elective surgeries (Gianoutsos, 2008). It is therefore essential that there should be an approach of â€Å"group and screen† procedure compared to going for the full cross-match once transfusion is compulsory and therefore orders must be placed accordingly (Gianoutsos, 2008). In order to avoid the occurrence of hepatitis and HTLV-III infections, an approach of predeposit autotransfusion was realized specifically in elective surgery. This facilitates the conservation of homologous blood and creates an awareness and understanding for the proceeds of autotransfusion (Rebulla, 1987). This kind of approach finds its way through the advancement in the use of preservatives. The method has the advantage over the homologous transfusion where an individual receives the donor’s blood and hence risk life with hepatitis (risk is 46%), malaria, syphilis, allergic reaction (risk is 20 -25%) and mismatches due to any technical errors (risk is 61%). It is therefore essential for planned surgeries to have an autologist transfusion of blood to eliminate risks as it speed up the healing process (Holm, 1981). In order to find out the extent to which autologous blood that has been donated in advance and is used by the patient during the process of elective surgery, a study was carried out where 4996 patients undergoing elective surgery, of these, 1287 patients placed order for cross-matched blood even though 590 patients were found to be suitable for predepositing blood suggesting unawareness about predepositing blood. Merely 5% (32 patients) of the patients predeposited the blood, still 4 amongst these got homologous blood. The study concludes that by predonation of blood 68% homologous blood transfusion could have been avoided (Toy, 1987). This is autologous
