How Often Is a 737 Serviced?
The Boeing 737 is a narrow-body, commercial aircraft that has been in production since 1967. It is one of the most popular aircraft in the world, with over 15,000 units delivered. The 737 is known for its reliability and efficiency, but like all aircraft, it requires regular maintenance to ensure its continued safe operation.
Scheduled Maintenance
Scheduled maintenance is the most important type of maintenance for an aircraft. It is performed at regular intervals, regardless of whether or not the aircraft is experiencing any problems. The purpose of scheduled maintenance is to prevent problems from occurring in the first place.
The 737 has a comprehensive scheduled maintenance program that includes a variety of tasks, such as:
- Inspections of the aircraft’s structure, systems, and components
- Testing of the aircraft’s systems
- Lubrication and cleaning of the aircraft’s components
- Replacement of worn or damaged parts
The frequency of scheduled maintenance varies depending on the age of the aircraft and the type of operation it is used for. However, most 737s undergo scheduled maintenance every 6 to 12 months.
Unscheduled Maintenance
Unscheduled maintenance is performed when an aircraft experiences a problem that requires immediate attention. This type of maintenance is typically unplanned and can be caused by a variety of factors, such as:
- Component failures
- Damage from foreign objects
- Weather-related events
Unscheduled maintenance can be disruptive to an airline’s operations, but it is essential for ensuring the safety of the aircraft and its passengers.
Major Maintenance
Major maintenance is the most extensive type of maintenance that an aircraft can undergo. It is typically performed every 5 to 10 years and involves a complete overhaul of the aircraft. During a major maintenance inspection, the aircraft is stripped down to its basic components and inspected for any signs of wear or damage. All of the aircraft’s systems are tested and calibrated, and any necessary repairs or replacements are made.
The Importance of Regular Maintenance
Regular maintenance is essential for ensuring the safety of an aircraft and its passengers. By following a comprehensive maintenance program, airlines can help to prevent problems from occurring in the first place and ensure that their aircraft are always operating in a safe and efficient manner.
