KATHMANDU: In the wake of the recent Saurya Airlines Bombardier CRJ-200 crash at Tribhuvan International Airport (TIA), the importance of aircraft maintenance protocols, particularly the C-check, has come into sharp focus. This tragic incident, which resulted in the deaths of 18 people, has highlighted the critical role of comprehensive maintenance checks in ensuring the safety and reliability of aircraft.
The Bombardier CRJ-200 aircraft involved in the crash was built 21 years and 4 months ago, raising questions about its maintenance history and adherence to safety protocols. One key aspect under investigation is whether the aircraft had undergone its scheduled C-checks.
A C-check is a thorough and detailed inspection of an aircraft, conducted approximately every 20-24 months or after a specific number of flight hours. Unlike the more frequent A and B checks, which are performed more regularly and cover basic maintenance tasks, the C-check involves a complete review of the aircraft’s systems and structures. This includes inspections and maintenance of the airframe, engines, landing gear, avionics, and other critical components.
During a C-check, the aircraft is typically taken out of service for several weeks. The extensive nature of this inspection allows maintenance teams to identify and address any potential issues that might compromise the aircraft’s safety and performance. The process involves dismantling certain parts of the aircraft for detailed inspection and replacing or repairing components as necessary.
The recent crash underscores the vital importance of these rigorous maintenance checks. Ensuring that all scheduled maintenance, including C-checks, are performed on time is essential for the safe operation of aircraft. The investigation commission, formed by the government and led by Ratish Chandra Lal Suman, will likely examine the maintenance records of the crashed aircraft to determine if any lapses in these checks contributed to the accident.
Prithvi Subba Gurung, spokesperson for the government, emphasized the need for stringent adherence to maintenance protocols. “The CAAN will be responsible for intensive monitoring of domestic airlines to ensure they comply with safety standards,” Gurung stated.
As the investigation progresses, the findings will be crucial in shaping future maintenance and regulatory practices to enhance aviation safety. The tragedy has already prompted the government to mandate regular testing of aircraft by domestic airlines and increased oversight by the Civil Aviation Authority of Nepal (CAAN).
Understanding and implementing comprehensive maintenance checks like the C-check is essential for preventing accidents and ensuring the safety of passengers and crew. The aviation community, regulators, and airlines must work together to maintain the highest standards of maintenance and safety in the industry.
