CURRENT VERSIONS: Both are An-74 derivatives in which podded, underslung engines of increased power replace the normal An-72/74 installation.
An-74T-300: Baseline transport for 52 passengers. As described.
An-74TK-300: Combi version. Internal dimensions as for An-74T-100/200.

DESIGN FEATURES: Revised engine installation decreases T-O run, despite loss of Coanda effect; new power plants reduce maintenance requirements and fuel consumption (up to 29 per cent); new position simplifies access. Compared to An-74T-200's range with 45 min reserves, An-74T-300 offers additional 372 n miles (690 km; 428 miles) with 10,000 kg (22,046 lb) payload and 518 n miles (960 km; 596 miles) with 5,000 kg (11,023 lb). Cruising speed (at nominal 10,600 to 11,000 m; 34,780 to 36,420 ft) also noticeably improved.
Cabin enlarged by repositioning of partitions; integral airstairs; upgraded air conditioning; improved instrumentation, including provision for LCDs.
