What is the interval for performing valve mechanism inspections after the initial 25-hour inspection?

The interval for performing valve mechanism inspections after the initial 25-hour inspection is set at every 100 hours. This frequency is established to ensure that the valve mechanisms of the aircraft are regularly checked for proper function and condition, which is crucial for the safe operation of the aircraft. Regular inspections help in identifying wear or potential issues that could lead to more significant problems if left unchecked.

Establishing such intervals is based on operational experience and maintenance practices, ensuring that aircraft are kept in optimal flying condition. By adhering to this 100-hour inspection schedule, operators can maintain safety standards and enhance the longevity of aircraft components. Therefore, it is important to follow this guideline in the maintenance schedule to ensure reliable aircraft performance.
