Can anyone explain and define the meaning in Airbus service manuals of the following acronyms: OTL and SLL?

Gemini,

OTL is "Operating Time Limit" for various items, such as T/R Driveshaft Bearings
Etc. These limits usually have an allowable margin for operational convenience.
The time limit may be in Hours or Calendar time.

SLL is "Service Life Limit" and is the ultimate allowable life of an item and has no
Margin allowed.

Regards,

Rigidhead

Some may find this table useful, but I hasten to add that I haven't checked it for accuracy!

Cheers RH. Some have explained to me that OTL's are recommended limits and not considered mandatory, but I don't think this is correct.

Thank you for the hint. I will relay it ... and get back as soon as I know what it was.
The warning unit output simply was too high. Reducing the output level via the poti helped to eliminate the problem.

Quick Question about Engine Fires in the AS350B2

May be a simple mistake or oversight, in the flight manual it states that when experiencing a fire in flight to switch off the booster pumps, while the Eurosafety App that I have for my phone doesn't include this step. Is this a mistake in the app or has there been some revision in the manual or elsewhere that I can't find?

EDIT: Never mind. I contacted Eurosafety and it was told that it was a mistake in the app.

Robertson Fuel Systems and Vector Aerospace to offer 'direct replacement primary fuel tank' for AS350, featuring
"multiple safety enhancements including all new modernized fuel retention technology, new components and increased fuel capacity (567 L vs. 552 L)."

In June 2011, Vector Aerospace was acquired by Eurocopter Holdings, the holding entity of the Eurocopter Group and a subsidiary of global aerospace and defense giant EADS.
Somewhat circular argument?

EASA AS350 Type Rating

Does any of you fine people know if it is possible to get an EASA AS350 type rating outside of Europe? Somewhere were it might be a little cheaper than in the EU?

Why the corrected weight chart and what is the catch behind it?
Hi.. did you find answer to this question of urs?

It sure is! A phenomenon of any single-system helicopter? Outside the approved flight envelope? There would be a few pilots who would disagree with that.

Shock horror - wazzing and zooming at high AUM and speed to show off to pax often leads to disaster!

As discussed on this forum before, the 350 has exactly the same problems with servo transparency/jackstall as the Gazelle so its not like it should have come as a surprise to Airbus/Eurocopter/Aerospatiale.

Every Brit Mil helicopter pilot trained on the Gazelle will have been shown the entry to and recovery from jackstall/servo transparency exactly because it is dangerous.

I remember it well - even to this day. It was something the instructor showed us literally hours into flying a helicopter and it was very scarey.
Dive to near Vne (163kts I believe) and then pull firmly back on the cyclic
I recall the Gazxelle lurching up and to the right (retreating blade side???). Completely out of control for about 1 or 2 seconds as it then automatically pulled itself out of Jackstall. The pilot then regained control.
I went on to teach it hundreds of times as an Instructor and loved doing it by then!
The MoD stopped it shortly thereafter because it was damaging the control runs.

I often wondered if anyone in civvy street came across this phenomena and until this incident never heard of anyone experiencing it.

Looks like a very very lucky man surviving this incident, so, too the pax

They are not exactly the same - the Gazelle is predictable - it is not necessarily so in the 350 as was found on several occasions in Canada. One of our guys had a run in with it on the ground.

How do you get jackstall on the deck FFS? You need to be on the extreme edge of RBS for starters???

He had a cyclic runaway during the preflight checks - he could bench press 180 lbs and couldn't stop it. Canadian helicopters had one too, though they didn't report it. Given that, to the French "servo transparency" means that the jack may as well not be there, to me that is a very similar effect (perhaps I should have said equivalent in the previous post). There have been reports of people getting it flying at 40 kts round a fire and coming off the top of a mountain. There is no way that the 350 version is as predictable as the Gazelle's, which does it every time, right on cue.

Ah, so it was a jack hardover as opposed to a jack collapse (which is essentially what jackstall/servo transparency is) That makes more sense.
