IO 540 Injection Tubes

Post by LouisCarre »

Hi,

There is a mandatory service bulletin for IO-540 and IO-360 about fuel injection tubings. SB342G. In fact you need to double the clamps that holds the injection tubes to the push rod tubes.

I did the bulletin for my aircraft and installed the clamps. Also you need to inspect tubes for cracks of any imperfections. What i did. Found all ok.

Today, I opened my cowling for inspection after 11 hours of flying. Surprise!!!! One tube cracked and blue traces inside cowling indicating that fuel has blowed to the engine compartment.... Gave thanks to God...

Noticed on last flight that engine was a little bit rough at full power...

Previous vibrations before the update on tubes made them at the end of their life...

Ordered all new tubes, no chance to take with others...

For those concerned, i think this is a good thing to know....

Regards,

Wow! Glad that turned out ok! I remember reading that SB and making sure it was complied with back when we had our Express Series 90 and its IO-540. Didn't realize there was still risk even after that all was done.

I would suggest to change tubes in prevention... life is more important than that price...

I noticed that this SB only applies to Lycoming. Just curious: any Continental-powered Expresses here?
