Let L.410 Turbolet / L.420
The PT-6A-powered prototype for the L.410 series first flew on April 16, 1969. Production versions include the L.410A, AF, M and UVP, which have Walter M601 turboprops.
The L-410UVP-E production version succeeded earlier variants and entered service in 1986. Its main changes included a modified interior to take accommodation to 19 passengers, a reinforced wing for optional streamlined tip tanks (boosting range by 40 per cent) and modifications to the 750 shp (559 kW) Motorlet Walter M601 E turboprops with five-blade propellers.
The L.410UVP-E version features a strengthened wing, and seating for four more passen-gers, taking total accommodation to 19. Military utility versions exploiting the L.410’s rough-field capability are available for a range of duties, including transport, medevac, para-dropping, and training.
More than 860 L-410s were in civil and military use by 1990.
A higher-powered L 420 variant first flew November 1993.
