How to Fix a Plane with Blown Engines: A Comprehensive Guide

A plane with blown engines requires meticulous and precise repair to return it to a safe flying condition. This guide will walk you through the necessary steps, ensuring that you understand the process and the critical documentation that must be adhered to.

Steps to Fix a Plane with Blown Engines

When an aircraft experiences blown engines, it is essential to follow a structured approach to diagnose, repair, and ensure the safety of the plane. Here are the steps to follow:

1. Confirm the Nature of the Malfunction

The first step in the repair process is to identify the exact cause of the blown engines. This can be done by reviewing the pilot's log entries, checking the computer fault history if available, and consulting the FIM fault isolation manual.

2. Test and Inspect the Engine

Once the nature of the malfunction is confirmed, conduct a thorough inspection of the engines. This will help in diagnosing the problem further and identify whether a simple replacement of parts is needed or if a complete rebuild is necessary.

3. Procure Replacement Parts and Schedule Repairs

Based on the diagnosis, gather the necessary replacement parts and schedule the repairs. It's crucial to follow the manufacturer's and FAA requirements to ensure the proper application and installation of these parts.

4. Conduct Repair Activities

Carry out all repair activities in accordance with the appropriate FAA and manufacturer requirements. This includes honing the cylinders, replacing piston rings, and, in some cases, boring the cylinders to the nearest acceptable size and installing new pistons and rings.

5. Test Repairs and Documentation

After completing the remedial activities, test the repairs as required by FAA regulations and manufacturer standards. It is also essential to sign off the work personally, using the privileges bestowed by the FAA to the Airframe and Powerplant license holder who performed the work.

6. Supervision and Finances

If you are working under the authority of a repair station or under the supervision of an Airframe and Powerplant (AP) inspector, the supervisory personnel should take responsibility for the work. It's important to note that there is no room for error in this process, as everything done to an aircraft must be documented and performed by trained and certified individuals using approved methods and parts.

Common Issues and Fixes

Some common issues that can lead to blown engines include a blocked PCV (Positive Crankcase Ventilation) valve or a blocked breather tube. If either of these is blocked, it can cause excessive blowby or oil leakage, leading to engine wear. In such cases, you might be able to fix the problem by replacing the piston rings, but this is often a short-term solution. For a more comprehensive fix, you may need to rebuild the engine, including boring the cylinders, installing new pistons and rings, and replacing all bearings and seals as well.

Conclusion

Fixing a plane with blown engines is a complex process that requires dedication, skill, and adherence to strict regulations. By following the steps outlined in this guide, you can help ensure that your aircraft is returned to a safe and functional state. Remember, the safety of the plane and its passengers is paramount, so it is essential to follow all necessary documentation and regulatory requirements.
