 Posted: Thu Mar 02, 2006 6:21 am Post subject: More Lycoming Crankshaft Troubles |
 |

Didn't know if more Lycoming troubles would be of any interest to folks on the list. But, just in case, looks like this time its a much larger group of people impacted. Interestingly these crankshafts are not "recalled" just "retired"?

More woes. Full story is at URL below if interested.

In what appears to be the largest crankshaft-related service bulletin yet, Lycoming has notified field shops and distributors that it's calling for the "retirement" of 5100 additional crankshafts in certain -360, -390, -540 and -720 series four-, six- and eight-cylinder engines. The newest action follows close on the heels of Lycoming's last recall of nearly 400 crankshafts for -360 series engines last fall and brings the tally of affected crankshafts to some 7500. While last fall's action was a "recall," the latest mandatory service bulletin -- SB 569 (PDF file, here) -- requires the retirement of serial-number-specified crankshafts within the next three years, by Feb. 21, 2009, or at the first opportunity before then if the crankcase is opened up for overhaul or prop-strike inspection. The distinction between "recall" and "retirement" is one that some owners may not like.
Lycoming's Michael Everhart said, "While there have been no incidents involving these crankshafts, Lycoming Engines, in cooperation with the FAA, continues to monitor and analyze the approximate 5100 affected shafts. Lycoming Engines is instituting this proactive retirement from service to be consistent with our long-standing commitment to product quality and our customers."

I wonder if they are overstocked or just need to sell more cranks/engines.
