(Walter Lannon) ________________________________ Message 1 _____________________________________ Time: 01:44:34 PM PST US Subject: Yak-List: Blown oil hose CJ - connectors? From: "jay-dub" It's all happening... Just prior to shutdown (luckily), the hose from the engine to the oil cooler let go just aft of the firewall but before the cockpit, resulting in hot oil spraying out and now seeping from just about every panel and flooding the right side of the cockpit. No injuries fortunately. We can replace the hose easily enough but the issue is the connectors. The existing ones don't appear to be reusable - unless someone here knows different. Are they standard AN connectors? If so, no dramas. If not, what are they and where can I get them please? -------- CJ and Yak-52 owner Read this topic online here: http://forums.matronics.com/viewtopic.php?p=471357#471357 ________________________________ Message 2 _____________________________________ Time: 03:15:57 PM PST US From: Doug Zeissner Subject: Re: Yak-List: Blown oil hose CJ - connectors? When some of mine were changed we used a pipe wrench with the hose firmly clamped into a vice. It marked them up a little but they were reusable.

They are definitely not AN fittings!=C2- They are metric.=C2- Remove th e hose and find a hose fabrication shop that will remove the ends off the h ose and reuse the metric nuts or give Cliff Coy a call at Border Air in Swa nton, VT.=C2- Cliff can remake the hose using your hose ends and metric h ose.=C2- 802-868-2822.Dennis From: jay-dub To: yak-list@matronics.com Sent: Sunday, July 30, 2017 4:45 PM Subject: Yak-List: Blown oil hose CJ - connectors?

That is a very disturbing report. Such a failure in flight could be catastrophic. These are old to very old aircraft, some in the order of 50 + years and the oil cooler hoses are very difficult to replace or even inspect. The oil out hose is probably the most critical one in the aircraft due to high temperature and the fact that scavenge pump pressure is unregulated. Were this a certificated aircraft there would likely be an AWD on the subject. Jay-dub could you provide some pics and description of the failure when you get a chance?
