Service history

1946

As already mentioned, at the beginning of 1946, six machines of the EMAer were off line for a programme of maintenance work. No 601, which had been in the workshops since the beginning of October, was eventually flown to Boiso Lanza where it was to remain under a continuing very slow maintenance schedule until May 1948!

These low priorities would get worse as far as the other DH82As were concerned in the course of the current year and the next.

The reasons for this situation are clear and logical: Military Aeronautics had continued to invest in new aircraft. In the last two years, four Piper AE-1, half a dozen AT-6 and fifty Fairchild PT-26 primary trainers of Canadian origin were ordered of which thirty-six were already in service. This whole new intake completely absorbed the time and effort of the workshop personnel in maintaining these more modern machines.

Also, in the United Kingdom the production of the Tiger Moth had ended and the procurement of certain spare parts was becoming difficult and un-economic. Nonetheless, and in accordance with the schedule, by March, the EMAer had three of its Tiger Moths ready on the line to be flown by seven Junior Lieutenants and two First Lieutenants as part of their respective Applied Courses and promotion.

On 7 April 1st Sergeant Hilario Almandós completed a series of five flights towing gliders from fields in the district of San Jose. This mission, which operated from the glider base at Melilla, was carried out in 607 and was one of the last exercises to be completed by this machine.

Two days later 603 reappeared at the School, after an 11 month overhaul at the DGTAG&S.

At this stage it became evident that the Armed Forces' budget could not provide the time and resources necessary to maintain the remaining twelve DH82A Tiger Moths in service.

After a careful evaluation, with technical assistance and logistics from the firm of Regusci & Voulminot and in consultation with the manufacturer, the decision was taken to reduce the fleet, grounding two aeroplanes which would be used as a source of spare parts.

Towards the end of April the Ministry of Defence and the DGAM published Order No 7592 which took Tiger Moths E-607 and B1-609 out of action. They had accomplished 1,845 and 1,728 flying hours respectively.

 

 

The Tiger Moth ignition switch

The Tiger Moth was at Aerial Base No 1, which was sited at Capt. Boiso Lanza Aerodrome before moving to Carrasco.

This aeroplane, which was for two people in tandem, had the engine ignition controls situated outside the cockpits on the left side decking. There were switches for the front seat and rear seat but if the switches of the rear cockpit were on, the one for the front cockpit would not turn off the engine.

Instructor Alvarado (a Sub Officer) was sitting patiently in the front cockpit with the engine running and with the aeroplane facing a group of officers who were waiting their turn to fly standing at a distance of about 12 metres.

As nobody came to his aircraft to take over, he decided to turn off the engine. It was customary to push the throttle forward as the ignition was switched off but when Alvarado turned off the front switches and advanced the throttle lever he realised the switches for the rear cockpit were on and the engine had not stopped.

The Tiger Moth had no brakes and was not chocked. The aeroplane gathered speed in the direction of the bench where the officers were sitting. There was much running, falling on the ground and leaping out of the way of the aeroplane which was approaching with sinister intentions, to the desperation of Alvarado. Two of the waiting Officers, however, had the wits to get hold of the wing tips and stop it.

Alvarado almost got a beating as they thought it had been a bad joke until it was proved that the rear switches were on.

In May, the “air sailing” activity was repeated.

On 11th and 12th First Lieutenant Almandós flew various glider towing sorties with 603 near the city of Minas in the district of Lavalleja.

According to notes in the official archives, this was the last glider towing mission to be carried out by the DH82As.

Between June and September, the EMAer would keep an average of three Tiger Moths in flying order. They were used for about 50 hours mainly associated with the training of Junior Lieutenants on their Application Course, which included several camera-gun practices in 603.

Once this phase was over, the activity of the EMAer Tiger Moths was finished for the year. The four aircraft on strength were flown to the DGTAG&S for maintenance work where 601 had already been for certificate of airworthiness renewal which had lasted for over a year and 607 had been put out of action.

Now let us see how the six machines assigned to the Bases were behaving.

The A.B. No 1, as already mentioned, lost 609 in April when it was put out of action and 605 was withdrawn from flying for the rest of the year when she was sent to the DGTAG&S for overhaul.

In compensation, 613 flew continuously for the next twelve months, achieving a total of 123 hours.

At A.B. No 2, 602 had a minor accident on July 19 about 30 km east of Durazno. The aeroplane turned over upon making a forced landing because of engine failure and would not be airworthy again until 1948. Its crew, Privates Lino Marquizo and Elso Acerenza were unharmed.

Aircraft 600, also on account of engine problems, made an emergency landing on September 30 and was out of action until March the following year.

Lastly, 611 was the machine of the year, flying 188 hours with no incidents.

At the end of 1946 the Tiger Moth fleet's airborne time totalled 723 hours use; 130 less than the previous year. Of the 10 remaining aircraft, only 611 and 613 were airworthy, one at each Base, whilst the eight others were out of service for repairs, inspection or overhaul.
