Best Laid Plans
The CH437 was the 'workhorse' in those early years, before the Chinook
and Skycrane aircraft became available. Heavy equipment and supplies were
needed in remote bases, as the build up continued. If not on stand-by to shadow
Air assaults (Recovery) varied missions were demanded of these machines.
A beast in size and power, they still needed to be handled carefully, as these finely tuned aircraft, tried to cope with the constantly changing conditions in Vietnam. Although no photo shots exist of this incident, a still from an 8mm movie is attached. In terms of balance, the 611th was also capable of 'sitting on a load' When these aircraft settled, there was usually only one winner. In Scotts own words.
So here is what happened the day that “Wooly Booger” sat back down on the Howitzer it was trying to sling load for Marvin The ARVN.
I remember that we got the call for the mission to move the gun along with some ammo from point A to point B. We knew that both the takeoff and landing areas were rough and dusty areas that would require that the engines be on filtered intake air rather than open ram air. That caused a small loss in power.
We asked that this mission be all set for early the following morning.
We arrived at the LZ early the next day in the ’37 and Sammie’s UH-1B. The ammo was there so we loaded some into the helicopter. Don’t remember how much but some. The fuses were going with Sammie. Lucky guy!!
So finally around 1000 or so the gun shows up. We hadn’t slung one of these before so didn’t know how to rig it but gave it our best shot. Well we had it rigged wrong of course and the muzzle of the gun tipped down to the ground. We had the pilot cut the load and to land but kept him turned up.
We re-rigged the gun and another guy and I did the hover hook up. After we got out of the way the pilots attempted the lift. And couldn’t get it off the ground for very long before the Nr would drop and she would come back down to the ground. They tried this a couple of times but no luck. Just too heavy with the included internal load of ammo.
You could start to see black smoke in both engine exhaust streams, an indication that the cylinder head temps were climbing towards or were at the red line.
The Bendix Pressure Injection carb had a setting called “Auto Rich” that would automatically start enriching the mixture going into the engine to try and cool it down a bit. At least that is my understanding of the process.
So had the decision been made to stop at that point, cut the load and move off to the side to cool the engines while we unloaded the ammo from inside, well that day would have turned out totally different. We could have made a second trip with the ammo.
But the decision was “Let’s give it one more try…”. And both engines failed and the helicopter sat back down on the load, with the armor plating of the upper right corner of the gun poking a good sized hole just forward of the APU on the left side aft of the aircraft. Behind the gunners window. So that was that…
My memory isn’t super sharp on what happened next over the rest of that day, but as I recall some radio calls went out and two engines were pulled from other CH-37’s, I believe at least one was from the 611th, and the gear and tools needed were flown to the site.
A Vietnamese wrecker operator was found and while he couldn’t speak English and we couldn’t speak Vietnamese, both engines were changed in record time and just at dusk she was ready for its first run up.
Again my memory isn’t 100% sure about all of this, but I do recall being up front when the W3 fired the engines up, the guys outside did a good leak check, and he said “Let’s get out of here!!” Stupid me asked “But sir, you haven’t done a mag check yet…” To which he replied “So Drew, if the mags don’t check out 100%, do you want to stay here and **** with them??” (it was getting dark out there)
I got his point. Scott
