What is the maximum time a 100-hour inspection may be extended?

A 100-hour inspection can be extended by a maximum of 10 hours. This extension allows operators some flexibility in scheduling maintenance without compromising safety measures. The rationale behind this limitation is to ensure that aircraft undergo necessary inspections and maintenance on time while allowing for operational needs, such as flight schedules or unforeseen circumstances.

Extending the inspection beyond 10 hours could potentially compromise safety and maintenance standards set by regulatory authorities. It's important for operators to recognize that any such extension must still prioritize the aircraft's airworthiness and comply with regulatory requirements. This understanding is crucial for maintaining safety in aviation operations.
