Aircraft Reliability in the Management and Operation or aircraft plays a pivotal role in the management and operation of aircraft as being a mandatory requirement to monitor and consider. Though the scope of a reliability program is often categorized using ATA Chapters, such as the ATA100 group, it’s not solely determined by it.
Reliability management doesn’t operate in isolation, and it requires collaboration with various stakeholders or areas for example. including Powerplant – looking at the engines and APUs, or structures – looking at the structural components of the aircraft. A cohesive strategy necessitates that all areas and stakeholders’ concerns are addressed, and there needs to be seamless flow of information. Reliability is sourced from multiple areas and this needs to be reported in a timely and responsible way. Such procedures and the associated information flow should ideally be documented, most notably in the Continued Airworthiness Management Exposition (CAME).
For an effective reliability program, the data collected should align with its objectives. It’s essential to segregate actionable insights from redundant information. For instance, routine maintenance tasks or defects that don’t influence the aircraft’s performance shouldn’t overshadow significant issues.
Maintenance tasks and maintenance visits vary in their significance and impact to reliability monitoring. While routine tasks planned for aircraft maintenance are straightforward, extensive procedures necessitate in-depth scrutiny – are there consistently non routine cards with findings or failures / component replacement or servicing carried out because of this inspection or function? The data input into the reliability program should be systematically analyzed against established criteria, either using alert levels or visual representation like graphs to pinpoint trends.
It’s vital to discern which sources of information are most pertinent to the reliability program. Some ATA chapters may offer guidelines on what to include or exclude. For instance, ATA 25 could be limited to safety-related defects and omit minor tasks like cleaning related entries. Similarly, routine filament changes (ATA 33), cold weather precautions (ATA 38), or fan blade damage due to unforeseen events (ATA 72) might be considered non-critical to the reliability evaluation.
The entire process hinges on well-defined sources of information and their flow. This could include for example tech logs (be it paper-based or electronic), component replacements, to technical delays or incident reports. Additional sources could encompass Aircraft Remote Monitoring, Maintenance Task Cards, Workshop Reports, or specific aircraft capabilities.
In conclusion, a well-curated reliability model emphasizes discerning actionable insights from routine tasks and ensuring a comprehensive approach to aircraft reliability, maximizing operational efficiency.
