    • Investigation: Corroded Propeller Blade Caused KC-130T Crash
      The Marine Corps determined that a corroded propeller blade that came off mid-flight was the cause of the July 10, 2017, crash of a KC-130T transport plane.

      That propeller did not go through proper maintenance the last time it was sent to an Air Force repair depot, which may have led to the damaged propeller remaining on the airplane that ultimately crashed and killed all 16 personnel onboard.

      One Marine has died, another is in fair condition and five are still missing after a collision between a fighter and a refueling plane off the coast of Japan, U.S. and Japanese officials said Thursday.

      The incident, which involved an F/A-18 Hornet and a KC-130 Hercules aerial tanker that took off from Marine Corps Air Station Iwakuni, happened at about 2 a.m. during “regularly scheduled training,” a Marine Corps statement said.

    • C-130 with rich heritage enhances training and readiness
      SHEPPARD AIR FORCE BASE, Texas – In late March 2018, an MC-130P Combat Shadow out of Moffett Federal Field, California, took its final flight to Sheppard AFB, where it would continue its legacy of supporting the Air Force as a maintenance trainer for Airmen in Training.

      This particular MC-130, which has been in combat in Vietnam, the Cold War and was even deployed to catch falling satellites, now serves as a part of the 82nd Training Wing’s Special Missions Aircraft Armament Apprentice Course and the C-130 Aerospace Maintenance Apprentice Course.

    • Dobbins flies tactical airlift training mission at Youngstown
      DOBBINS AIR RESERVE BASE, Ga. – Rays of sunshine pierce through the cargo bay windows of a C-130H3 Hercules. The monotonous rumble of the engines make the plane’s flight almost peaceful. Suddenly the aircraft goes into a hard left bank. The gravity inside the aircraft seems to triple as the g-force takes effect, pinning everyone to their seats.

    • US to boost nuke sniffing with modified C-130s
      When the Air Force dispatches aircraft to the Asia-Pacific to monitor the atmosphere for signs of nuclear activity from North Korea, it relies on its WC-135 Constant Phoenix nuke-sniffing planes. But with only two of those in the service’s inventory, it’s possible the WC-135s might not be able to respond to every contingency.

      Enter the ever-versatile C-130 Hercules, which now can be equipped with a modular kit that allows it to detect nuclear particles in the atmosphere.

    • NTS Failure
      By Ahmer · Posted
      Yes if NTS system fail prop RPM will be more then power section at that time propeller RPM cross the limit 103.5 . it should be pitch locked and aircraft will yaw opposite direction. If Negative torque increases limit -6000 torque  RGB Decoupled from power section. Definitely if outer engine is pitch lock and pilot not confirmed  the torque should be more when throttle retarted & aircraft will be yawning opposite direction.we experienced of Pitch lock during NTS system failure during decsanding,Fault is with NTS bracket which not properly actuate NTS system.

      You are missing the point on NTS in this condition. "Hi speed" dives are not a normal profile and this condition (NTS induced by hi speed airflow) is very rare especially with power on. Flight idle descent is common but airspeed is usually limited to prevent NTS (airframe limitations)  We usually see NTS at Flt Idle once we arrive at lower altitudes as the air gets more dense and we add a small amount of power to eliminate the NTS condition.   NTS is a DIRECT input to the feather valve and bypasses the normal governor.  If there is an onset of NTS during a hi speed dive and a failure of the NTS system does not increase blade angle; drag will increase and the aircraft will yaw (original posters question) additionally pitchlock while it could/would come into play if the Rpm INCREASED TO 103.5 it is not a factor because the blade is not trying to decrease and while the normal governor should increase the blade angle to maintain RPM we are discussing failures not normal operations and the feather valve should have already commanded a blade angle increase. It is important to remember if the NTS continues to increase at aprox -4000 inlb TQ the prop should decouple which would actually be a very bad situation because the increase airflow which caused the NTS would now drive the "pitchlocked" propeller very fast and cause even higher drag.

      NTS system works above flight idle, NTS system work when prop try to rotate engine (during descending,gust load,interruption in TD system,and improper governing) when propeller try to rotate engine (negative torque ) produce this system increase the blade angle when blade angle increase prop RPM decease  become in governing range RPM.                            If ur NTS system fail during descending & NTS system not increasing blade angle through feathering valve and propeller RPM increases obve the pich lock RPM limit ( above 103.5) then propeller should be pitch lock. U can observed pich lock propeller by moving the throttle forward engine RPM follow the throttle movement & torque will be same its indication of pitch lock. REGARDS

      High speed anything in the Herc is rare BUT in the case of dives there is the ability to have an increase in airflow through the prop which could cause NTS. This could happen with the throttle at flight idle power off or with power on at any setting above flight idle.   As the airflow increase the prop wants to drive the engine as the air becomes the drive force not the engine power.   IF the NTS fails to increase the blade angle drag will be induced; an outboard prop will have more yaw effect than an inboard prop.     Would the prop pitchlock is a dynamic question and is dependent on the situation but in reality pitchlock prevents the prop from decreasing blade angle therefore again in theory the blade should continue to increase blade angle.   ANYONE have the OLD 1960s "PROPORGANDA" illustrated little book that had all the little "engineers" and "mechanics" drawn in? There are some good explanations on this and other prop engine related topics.

      Looks like the old 1C-130H-2-4 manual. It has some really interresting graphs, although i dont remember anything to do with bleed air in it
    • Investigation: Corroded Propeller Blade Caused KC-130T Crash
      By c130fe · Posted
      Mr Heflin; So wrong on so many levels.  I suspect you've never been involved in aircraft maintenance and witnessed the inspection complexity and the hundreds of people who are involved over a long period of time. I was a C-130 USAF crew chief for several years and a flight engineer for over 20 years; including the civil commercial model; L100. The flight engineer inspects the props prior to flight standing on the ground looking up at the blades for obvious defects.  Corrosion is not an obvious defect. Its not like the obvious, visual corrosion on your boat .  It's hidden and requires Non Destruction Testing to find it. The major player here is the depot.  They have the equipment and the trained NDT inspectors to find corrosion.  They are paid to perform proper depot level inspections. These depot inspections are considerably more complex than what can be performed at the squadron field level. 
      When I first learned of the crash I assumed a wing had failed, that's a well known issue.  A blade breaking off is rare indeed.  I remember once that it happened on an A model about 100 years ago but did not cause a crash.  
      I pray for the lost lives.

      An artist asked the gallery owner if there had been any interest in her paintings that were on display. "Well, I have good news and bad news," the owner responded. "The good news is that a gentleman noticed your work and wondered if it would appreciate in value after your death. I told him it would and he bought all 10 of your paintings." "That's wonderful," the artist exclaimed. "What's the bad news?" "The gentleman was your doctor."

      One day a housework-challenged husband decided to wash his sweatshirt. Seconds after he stepped into the laundry room, he shouted , 'What setting do I use on the washing machine?'
      'It depends,' his wife replied. 'What does it say on your shirt?'
      He yelled back, ' GO BUCKEYES!'
      And they say blondes are dumb.

      A farmer in the country has a watermelon patch and upon inspection he discovers that some of the local kids have been helping themselves to a feast. The farmer thinks of ways to discourage this profit eating situation. So he puts up a sign that reads WARNING; ONE OF THESE WATERMELONS CONTAINS CYANIDE!   The farmer returns a week later to discover that none of the watermelons have been eaten, but finds another sign that reads, NOW THERE ARE TWO!
