Narciso Pillepich was from St. Polten (Austria).

On 12 June, the 2^o Stormo’s fighters were joined by those of the 10^o Gruppo (84^a, 90^a and 91^a Squadriglie) of the Gorizia based 4^o Stormo C.T.. The Gruppo was commanded by Tenente Colonnello Armando Piragino and started the war at Tobruk T2 with 27 CR.42s.
At the beginning of the hostilities the 84^a Squadriglia C.T. was composed of the following pilots: Capitano Luigi Monti (CO), Capitano Aldo Lanfranco, Tenente Vincenzo Vanni, Maresciallo Emiro Nicola, Maresciallo Mario Bandini, Sergente Maggiore Ugo Corsi, Sergente Domenico Santonocito, Sergente Roberto Steppi, Sergente Giuseppe Scaglioni, Sergente Corrado Patrizi and Sergente Pillepich. The eleven pilots had only eight Fiat CR.42s. It seems that Sergente Maggiore Corsi and Sergente Pillepich didn’t take part in the move of the unit from Gorizia on 7 June but were however in T2 with the unit from at least 13 June and 15 June.
On 12 June, the first fighter of the 10^o Gruppo to arrive at El Adem T2 was that of Capitano Luigi Monti, who landed in the morning. His Squadriglia’s mates arrived later, obliged to turn back by the bad weather. Then the other Squadriglie followed.

At 07:45 on 19 June, four Gladiators from 33 Squadron flown by Squadron Leader D. V. Johnson (N5782), Flight Lieutenant G. E. Hawkins (N5765), Flying Officer A. H. Lynch (N5764), and Sergeant Roy Leslie Green (L9043) accompanied by Flying Officer Peter Wykeham-Barnes (Hurricane Mk.I P2639) of 80 Squadron and two Blenheim IFs from 30 Squadron took off from Mersa Matruh to patrol between Bug Bug and Sollum.
At 09:40, they sighted a formation of nine Fiat CR.42s (in other sources it is stated that it was five CR.42s and either seven CR.32s or Ro.37s). The Fiats were slightly below and to the port side of the British fighters, who were in an ideal position to make an attack.
Wykeham-Barnes shot down the leader of the Italian fighters whilst he was doing a vertical turn, with a short burst at full deflection. The Gladiators claimed two more CR.42s, but lost 24-year-old Sergeant Green (RAF No. 44754) when he was shot down despite some violent aerobatics.
The returning RAF pilots reported that although the enemy was superior in numbers, they lacked the aggression of the Gladiator pilots and gradually retreated towards the Libyan border. Wykeham-Barnes found it difficult to get his sights on the Fiats, because they were so very manoeuvrable, but eventually one of them made a mistake and he was able to get in a good burst of shells, which caused the CR.42 to dive away with smoke trailing behind it. He did not actually see it crash, but it was later confirmed as being destroyed by the ground forces. The Gladiators and the Hurricane were then forced to break off the combat by lack of petrol and ammunition. On their way back to Mersa Matruh they had to land at Sidi Barrani to refuel and rearm. The Gladiators were back at 10:10 and Wykeham-Barnes at 10:30.
The Italian aircraft had been from the Tobruk T2 based 10^o Gruppo C.T. At 08:40, five aircraft of the 84^a Squadriglia took off to escort a formation of five Breda Ba.65/A80s of the 159^a Squadriglia, 12^o Gruppo Assalto and nine CR.32s from the 8^o Gruppo, heading to attack enemy vehicles between Sollum and Sidi El Barrani. The Bredas took off at 07:20, commanded by Capitano Duilio Fanali. The Italian fighters of the 84^a Squadriglia were flown by Tenente Colonnello Armando Piragino, Capitano Luigi Monti, Sergente Maggiore Ugo Corsi, Sergente Giuseppe Scaglioni and Sergente Pillepich (almost certain MM5552). Monti, who was the pilot with the longer war experience insisted with his commander to increase the number of aircraft participating in the escort, but without avail. The assault planes were out in a search-and-destroy mission and firstly they had to find targets. In doing so they started with a pass between Amseat and Bardia, then a second one going beyond Sollum then a third one. In this way, a lot of time was lost and the RAF could scramble its aircraft. The Fiats were over the Bredas, turning at 2000 metres when a number of Glosters and Hurricanes (the Blenheims were not seen at all while the Hurricane was, as usual, misidentified as a Spitfire) suddenly attacked them. After a sharp engagement, three pilots came back to T2. The missing pilots were Corsi and Piragino. A CR.42s (Corsi, who was killed) was clearly seen to fall into the sea after being hit by a Hurricane, while nothing was known of the second CR.42. The Ba.65s came back safely, without seeing enemy planes that were obviously too busy with the 4^o Stormo planes and didn’t engage them. However, returning to T2, the Breda flown by Sergente Maggiore Pietro Scaramucci suffered an engine breakdown and crash-landed, being written-off as a consequence.
Sergente Giuseppe Scaglioni returned claiming a Gladiator (probably Green) and a damaged Spitfire, Sergente Pillepich claimed two damaged Gladiators and Capitano Monti claimed a damaged Gladiator. The same evening a “British communiqué” advised that six (!) British fighters were lost in exchange for two Italians. So all participating pilots in this combat were credited with six shared victories because this was the only combat of the day for Italian units. Some days after, a British message dropped on Bardia informed that Piragino was wounded in a leg after crashing at Sollum and prisoner. Scaglioni described the combat:

“Over Bir el Gib we were surprised by a number of Glosters and a Hurricane that attacked with height advantage giving us a lot of trouble. I saw the commander doing a violent overturning while I was doing a break on the left, this manoeuvre put me behind a Gloster that I shot down with my 12,7 mm guns.
I lost sight of the commander immediately and after landing I knew he was missing. In the same combat we lost Sergente Maggiore Corsi shot down by a Hurricane that I attacked trying to distract it from its action but in vain. For sure Corsi was taken by surprise because he was considered a pilot of exceptional skill and the very best aerobatic pilot of the Stormo.”

On 11 September, the 9^o and 10^o Gruppo were still employed in standing patrols over the troops. During the second patrol of the day, at 17:45 in the Sidi Omar – Bardia area, a Blenheim was discovered at 6000 metres.
The Italian formation was escorting three CR.32s and was led by Maggiore Carlo Romagnoli. It was composed of seven CR.42s from the 84^a Squadriglia (Capitano Luigi Monti, Capitano Vincenzo Vanni, Tenente Giuseppe Aurili, Sottotenente Paolo Berti, Sergente Roberto Steppi, Sergente Pillepich and Sergente Domenico Santonocito), five CR.42s from the 91^a Squadriglia (Capitano Giuseppe D’Agostinis, Sottotenente Ruggero Caporali, Sergente Maggiore Leonardo Ferrulli, Sergente Elio Miotto and Sergente Alessandro Bladelli) and six CR.42s from the 90^a Squadriglia (Tenente Giovanni Guiducci, Tenente Franco Lucchini, Sottotenente Neri De Benedetti, Maresciallo Omero Alesi, Sergente Maggiore Angelo Savini and Sergente Bruno Bortoletti).
Capitano Vanni, Tenente Aurili and Sergente Steppi attacked first, followed by other pilots of the formation. During the combat Vanni’s aircraft was hit by return fire and with the compressed air piping pierced, he was forced to turn back. His wingmen continued the pursuit and claimed the Blenheim shot down.
The bomber however was assigned as a shared to all the 10^o Gruppo pilots presents (even if, for example, it is known that 90^a Squadriglia pilots totally used only 140 rounds of ammunition so possibly only one of them was able to use his guns).
This claim can’t be verified with RAF sources, but it is possible that it was a Blenheim from 113 Squadron since this unit’s ORB is lacking.

He was decorated for flying night fighter Re.2001s in 1943.

Pillepich ended the war with 7 shared victories, these being claimed while flying the Fiat CR.42.
