News from Ausfly seminar

[jetjr]

Good presentation from Keith Rule, Jamie and later from Rod re aircraft design

 

New oil from Aeroshell coming, being extensively tested and will be released and approved shortly. Specially for Jabiru engines. Not really a new formulation but highly suitable and will reduce carbon deposits.

 

Semi synthetic, will out perform 15W50 in cold weather warm up

 

Suggested not for use on engines older than ~200hrs as can could cause glazing with released carbon. OK after rebuild though.

 

No further need for run in oils proposed.

 

All oils should be replaced after 25hrs, filter at least 50hr if you are that tight.

 

Best oil currently is W100+.

 

15W50 is not a great selection

 

Once released Jabiru will alter manuals etc to allow new oils use.

 

New cold start kit. New coil assembly allows bigger spark at lower rpm. Available soon

 

New prop coming for 2200, 3300 afterwards. Ground adjustable (fixed with pin at factory). Current blades from Bolly look excellent. Glass blades, more speed, special 4 bolt hub.

 

Expected similar price to current offerings

 

Saw some scary pictures of maintenence on Jab engines, often from professional workshops. Shows people dont read or understand manuals or SB's

 

A warning that RAA self maintenance is under the spotlight

 

Sure Ill remember more later on. OME was there apparently and might have more to say?

No. You've said most of what I wanted to say. Thanks.

 

The thing I took away from the seminar was the need to read the SBs deeply. This applies to interference between those 12 point nuts and the cylinder, and some other spots. Apparently the relevant SBs refer to this problem.

 

I'm going to ditch what 15W50 I have in stock and only use W100+ on the 200Hr + engines. I'll consider the new oil in light of the ages of the planes we service.

A warning that RAA self maintenance is under the spotlight

Any more info on this little snippet?

Any more info on this little snippet?

Probaly CASA pushing RAAus to follow the NZ model where ALL Ultralights (Microlights) are given an annual inspection by a RAANZ / SAC Technical Inspector or LAME.

 

There is normally no charge for these inspections as I understand it IF carried out by a TI. The Technical Inspectors are similar to RAAus L2's or higher.

I understand that self maintenance is still OK in NZ, but yes, the annual inspection is a requirement (which I don't mind to be honest).

 

New Zealand is a country with a fairly heavy inspection regime. For instance, every six months, car owners have to obtain a Warrant of Fitness (WOF) ....similar to the annual 'Pink Slip' in New South Wales.
