Life can be cruel. |
This is just a short story but for me! it will never go away.
First let me explain a bit about Aviation Engines in particular.
As Pilots when we get into an aircraft, we have to have a little faith that the pilot before us, treated the engine with respect (As per the manufacturers Guidelines" which basically means No! hot starts! No! over boosting! or running hot! all things that would point to a possible engine failure, important considerations when you're expected to depart on a 1500 mile ferry over wild terrain and water. ( get my point?)
Now to my story:
I had just returned to South Africa for the fire bombing season and was sent south to pick up a second hand Thrush turbine,
which was to be used by me for the season.
The Thrush was a relatively new aircraft on the Agricultural scene and many of the pilots had only read a book and started flying them! even the operators seemed to have not picked up on the maintenance schedule, set out by the manufactures.
The difference is alarming an engine that is monitored correctly during its life, may go as much as 9000 hours before being changed! unmonitored engines may be changed at 2 to 3000 hours. when you consider the cost of an engine $ 100,000. It's a no contest decision.
I'm sure if the operators had realised this! they would have sent their pilots off to the factories for training.
Now I don't have a problem with this, but most of these guys didn't seem to know! To them all aircraft fly the same. crazy?
But they didn't seen to realise the turbine was so different! they just treated it like a piston engine with more power.
Back to my story:
Boss Terry had asked me "to give the aircraft a good inspection before taking delivery and if I found any thing that looked like a problem, not to take delivery, without talking to him first".
so as I walked into the company office, of the company we were buying it from, I introduced myself.
After a few pleasantries, I asked "to see the aircraft" it was parked on the front with a couple of other Thrushes, so I walked out to give it an inspection, after spending a good 2 hours checking over every part of the aircraft I could get at.
I decided that the airframe and all the attachments were in excellent condition.
On turning on the master switch, I noticed the battery was below start up power, this could indicate that the battery required replacing, or the alternator was faulty.
I went into their hanger and asked to borrow a meter to check out the starter motor and alternator as it functioned as one unit.
As I returned to the aircraft, one of their pilots, who must have been watching me, came over and asked "was there a problem"
I mentioned "the battery seemed flat" He said "that's not a problem
It's been flat for a couple of weeks and they have been Hot starting it, when they used it"!
I was amazed and visible taken back that a pilot would admit such a thing, he looked at me and asked me "did I know what a hot start was?"
"As he had done them a few times on this aircraft and he was willing to show me how its done"!
I declined his offer and said
"yes I have heard of hot starts" and I am also aware that there is a good chance that the engine could explode during this type of crazy cycle and another thing! you may have voided the manufacturers warranties in regard to this engine.
They could declare this engine as scrape!"
"You obviously have no idea of how to operate a turbine so please go away" he walked away, I could tell he felt he had said to much.
I found the fuse on the alternator side of the starter blown. so I returned to the hanger.
I asked for a battery jump start and they said "they would start it by a " Hot Start" again."
I was amazed I asked "who advised them to do "Hot Starts"? they just looked at me, I said "I want a fully charged battery trolley to start the turbine" OK? which I got. So I started the turbine and it was all in the green, I pushed in the alternator fuse and immediately the charge started to flow to the battery.
I taxied over to the aircraft run up area and carried out power and propeller test, which were fine by the way.
I returned the aircraft to the parking bay and shut her down and had another quick inspection of the engine for oil leaks and burning smells.
I removed the key to stop anybody from starting it again.
I walked over and entered their office again, the company owner and chief engineer were awaiting me, I said "I would have to call my employer and give him my report and he will talk with you direct".
"But I must warn you! I'm tempted to report this to the Civil Aviation Authority, they started to protest and I said " you guys are flying Turbines around the sky, with a load of untrained Pawnee Pilots"! "Really it's unbelievable."
"Now I will return to my Motel and speak with Boss Terry and he will Phone you."
The Chief Engineer gave me a run down to the Motel, on the way he made up a few excuses, saying his "boss had put him under pressure to keep the aircraft airborne and working".
I said "now look, you were quite willing to allow me to fly away in that aircraft, knowing hot starts had been used on it, I could have been killed, So please shut up".
