Boarding small aircraft there is a necessary weigh-in of passengers, eg the Islander. On the take-off run, as a passenger, you feel if the aircraft is heavy, as it bumps up and down on the gear quite sharply as it rolls when heavier.

Interesting piece looking at volume of notices provided to pilots, denting their effectiveness and contributing to safety incidents.

I have been saying this for years. Pages and pages of absolutely useless information within a set of notams and an actual important piece of information buried in the middle of it.
I know some operators have tried to highlight words like "closed" because it could relate to something important. They definitely need to reduce clutter.

Our NOTAMS are divided into departure ‘ destination alternate airports, followed by airspace, then enroute airspace. This is where it gets interesting, watching the countries like Greece and Turkey fighting through notams is mind numbing.

The alphabet vomit.

The joys of the provision of ATS in delegate airspace over international waters.
Or any disputed territory for that matter.

Passenger throws coin into plane engine for 'good luck' :eek:

A passenger hoping to fly with some good luck ended up having the entire flight cancelled after he threw coins into the engine of the plane. Yes, the passenger actually threw metallic coins into one of the propellors of the flight, thinking it can bring him good luck.

The incident reportedly took place at an airport in Weifang. A male passenger, identified with the last name Wang, was scheduled to fly from Weifang to Haiku on a Beibu Gulf Airlines flight GX8814 when he threw a handful of coins into the engine.

Fortunately, the staff was soon alerted about the coins in the engine after workers found coins on the ground during the pre-takeoff inspection.

Mid air collision involving a Cirrus and a MetroJet, incredible that everyone involved walked away.

That was quite the spectacular escape. One that will go down in the annals of aviation accident history.

Stovepipe · 14-05-2021 2:11pm

The guys flying the Metroliner are probably earning less than the guy who owns the Cirrus. regional airline pay in the US is pretty poor.

mr.anonymous · 14-05-2021 3:51pm

Not many GA aircraft have an in-built parachute like the Cirrus. Perhaps another type would have had a different outcome.

14-05-2021 3:53pm

They were lucky for that outcome in the Metroliner, considering it has a reputation for being a bit unforgiving at the best of times, let alone when almost severed in two by the passage of another aircraft.

There's a perception among some detractors that the parachute leads to poorer airmanship because the option to pull it and resolve an otherwise unrecoverable incident is there.

I don't buy that myself. I think it's unlikely anyone would be more cavalier in their flying because of the perceived get out of jail card the parachute offers. That's just madness.

Worth noting that the Metroliner was single pilot ops on a cargo flight. Guy was cool as a cucumber. I doubt there's even a door to the flight deck on that type, so he would have realised the cabin got a whole lot breezier all of a sudden.

There's no door between pilots and passenger/cargo area.

The ATC recordings suggest he thought he had a right engine failure but maybe there are elements missing:

Reminiscent of the "convertible" Aloha Airlines 737 :eek:

I'd say he did have right engine failure, probably ingested debris from the fuselage! Surprised on the audio it doesn't sound like there's much background noise, he's not even raising his voice.

cml387 · 18-05-2021 11:23am

Purely by coincidence last night I was watching a Youtube video of a Brit taking a Metroliner from Denver to the US's least-used lower 48 airport, somewhere in the boondocks of Nebraska. He was saying that the Metroliner was a rare bird now in the States.

Such an "unnecessary" outcome, but thankfully not fatal. Using mogas, lapstrap only, and the almost tragedy of life that could have been lost "landing" in a well-chosen field under the circumstance. Better to allow it come down "in the rough" than what happened. I once had an experience of landing "in the rough" and usually you will get either very abrupt braking action or at worst some aircraft damage rather than very serious injury, A stall crash like this inevitably causes serious vertical impact. It was a near thing.

Stovepipe · 16-06-2021 12:36pm

Im not a fan of the standard shoulder straps in 172s. They can slip off the lap strap very easily and they are about as effective as the belts on a Hillman Hunter. Most 172 operators refit modern four-point harnesses.

Gaoth Laidir · 17-06-2021 9:41am

3.2 Probable Cause
Loss of control due to stall and wing drop of the left wing at a low height during a forced
landing following a detonation-induced engine failure.

3.3 Contributory Cause(s)
1. Loss of airspeed during the final moments of the landing.
2. The aircraft was routinely operated on automotive gasoline (Mogas), which was not
approved for use and is less resistant to detonation than the approved fuel (Avgas).

Why in the world would someone use Mogas if it's not approved for that aircraft?

Stovepipe · 17-06-2021 3:45pm

Mogas is not approved for use on fuel injected engines as it can cause vapour lock in the fuel lines. Apart from that,people use it for convenience when they can get it from their local petrol station,especially high turnover stations. Avgas is more expensive by at least a euro a litre and drives up the hourly cost of running an aircraft. It is not often available at the smaller airfields and private strips as the cost of fitting out an approved Avgas pump and associated tank and plumbing is very high. Mogas is allowed to be used on some carburetted engines.

To be honest I find that explanation a bit bizarre. If someone's worried about the price of Avgas then they really shouldn't be in aviation. Knowingly putting Mogas in when it's not approved seems just plain madness...and criminal, I would suggest.

Frightening to think of what could have happened if the engine had failed over a town or City very lucky they were over fields.
