Fatigue critical structure refers to parts of an airplane that are at risk of developing fatigue cracks. These cracks can lead to severe failures, potentially resulting in catastrophic incidents. This classification is determined based on specific criteria outlined in aviation regulations. Structures that fall under this category may include both original components and those that have been modified or repaired.
This term is primarily used in aviation law, particularly in regulations concerning aircraft safety and airworthiness. It is essential for manufacturers, engineers, and maintenance personnel to understand which parts of an aircraft are considered fatigue critical. Proper identification and management of these structures are vital for compliance with federal aviation regulations, ensuring the safety of air travel.
Here are a couple of examples of abatement:
For instance, the wing structure of a commercial airplane is often classified as fatigue critical due to the stresses it endures during flight. If repairs are made to this structure, engineers must ensure that the integrity of the material is maintained to prevent fatigue cracking.
(Hypothetical example) A small aircraft undergoes modifications to its fuselage. If these modifications are not properly assessed for fatigue risks, they could lead to structural failures during operation.
Key regulations include:
| Term | Definition | Difference |
|---|---|---|
| Fatigue critical structure | Parts of an airplane at risk of fatigue cracking. | Specifically related to aviation safety and regulations. |
| Damage tolerance | Ability of a structure to withstand damage without failure. | Focuses on overall resilience rather than just fatigue. |
If you are involved in aircraft maintenance or modifications, ensure that you understand which structures are classified as fatigue critical. Regular inspections and adherence to regulatory guidelines are crucial.
