    අලුතෙන් ගන්නේ අවුරුදු 50ක් විතර පරණ තහඩු කෑලිද බන්?
    අපි අපේ පාවිච්චියට වාහනයක් ගද්දි කොච්චර දේවල් ගැන හොයනවද?
    රටේ අනාගත පාවිච්චියට මේ වගේ යානාවක් ගද්දි කොච්චර දේවල් බලන්න ඕනද බන්
    කෝටි ගණන් කොමිස් ගහල තහඩු කෑලි අරගෙන වටිනා තරුණ ජිවිත නැති වෙනවා.
    expectancy එක වැඩි වෙලාද දන්නේ නෑ කඩාගෙන වැටුනේ ??? :confused2:

    As I posted on another thread this aircraft could be new. A brief search shows that (Daily Mirror - 19 Oct 2018)....

    <snip>
    "Six brand new PT-6 aircraft purchased from the China National Aero-Technology Import & Export Corporation (CATIC) for primary training of the Sri Lanka Air Force (SLAF) has joined the SLAF fleet.
    Air Force Commander Kapila Jayampathy signed the formal final acceptance of the aircraft after they were assembled at the Aircraft Engineering Wing (AEW) at SLAF Base, Katunayake on Wednesday.
    Air Marshal Kapila Jayampathy signed the acceptance of the aircraft at AVIC Hongdu in Nanchang, China on May 15.

    In 2015, the National Security Council approved the request to purchase the six PT-6 aircraft at a cost of more than USD 5 million.

    PT-6 has been widely used by China’s Air Force and countries such as the United States, Pakistan, Bangladesh and Sri Lanka.
    PT-6 aircraft is a single-engine, tandem seat propeller trainer capable of performing primary flight training. "
    <snip>

    That's what was published in the Daily Mirror. However, please note that, apart from the above the PT-6 is quite old. Here's a brief history on the PT-6.

    It was first designed & built by Pratt & Whitney of Canada in the 1960's, when the piston engines went almost obsolete.
    The prototype of the PT6, an engine originally known as the DS-10, ran on a test bench in February 1960. Subsequent improvements were made and the engine was ready by mid - 1961.

    Around May 1986, Pratt & Whitney Canada Incorporated, and a Chinese state-owned firm, Zhōngháng Jì Jìn Chūkǒu Yǒuxiàn Zérèn Gōngsī, or China National Aero-Technology Import and Export Corporation (CATIC), signed a 5-year agreement to assemble a version of the PT6 from sub-assemblies made in Québec. This is where the Chinese version originated.

    In the 1990's the PT-6 was replaced by the improved PW-200. But having said that, in 2020, nearly 60 years after its first bench test, the PT-6 remained one of the most popular turboprop / turboshaft in its class.
    In Business Aviation alone, there are over 20,000 units of the current series PT-6A engines have been installed in 54 different makes/models - eg: Beech King Air series the most prolific platform (10,774+ engines and counting), followed by the Cessna Caravan series (2,573+). The out-of-production Piper Cheyenne comes in third with 1,954 engines. This count does not include the units purchased by several countries for military use.

    Our "Air Farce" (not a typo) had paid 5 Million for six units... I am not so sure about the purchase price though. When it comes to purchasing stuff we know what usually happens... Remember the infamous Mig deal and others. :oo:

    මම aircraft ගැන දන්නේ නෑ. aircraft ගැන overview එකක් දුන්නට ස්තුති.
    මම කතා කලේ මේවා 1976 හදපුව නම් මේ වෙද්දී අවුරුදු 50කට ලගයි වයස.
    ඒ රට වල අවුරුදු 40ක් කඩා නොවැටි තියෙන්නත්, මෙහෙ නග්ගපුවම කඩා වැටෙන්ඩත් හේතුව පොඩ්ඩක් හිතපන්.
    මේවා expired බඩු. මේවගේ expiration එක check කරන්න අපේ කොල්ලෝ ජිවිත වලින් වන්දි ගෙවන්න ඕන.
    අන්න ඒ ගැනයි මම කතා කලේ.

    This is not the first time we lost aircraft and or life pilot etc. First we must find out the cause. This is a military craft so it needs to be done by respective authorities with necessary skills. Facebook news creators or paper reporters cannot be relied upon.
    Our corruption at high places cannot be attributed to all disasters but cannot be rules out either.

    FYI

    What you have written is about Canadian made PT-6 turbine engine.
    Aircraft that went down yesterday was Nanchang PT-6 (export version of Nanchang CJ-6A) powerd by Radial piston engine. This aircraft has no ties to Canada.

    Sorry.. I thought as per the Daily Mirror news item it's PT-6 from CATIC which they were assembling under licence from P&W. If it's Nanchang CJ-6A why did it cost millions... for a tin can where you need a pilot who can fly and also pray. :oo:
    But I believe you are correct as the news item also says....
    "Air Marshal Kapila Jayampathy signed the acceptance of the aircraft at AVIC Hongdu in Nanchang, China on May 15." - which I missed on the first reading.
    Another fishy deal.... Wonder anyone would pay $100K for a Nanchang. :no:
