Rates proxied from the mechanically identical Beechjet 400 (same airframe post-Beech acquisition): broker quotes $3,000-$3,500/hr (Jettly, Mercury Jets, Paramount Business Jets, 2025-2026). No Brazil-specific charter rate found for this type.

How we read this price · 7 sources · researched 04/06/2026

Discontinued early-1980s light twinjet; Diamond II is the rarest variant (only ~8-11 built 1985-1986 w/ JT15D-5 engines, all later converted to Beech 400; design sold to Beechcraft Dec 1985 -> became Beechjet/Hawker 400). Pricing triangulated: VRef $225k(1982)->$300k(1985) via AOPA Quick Look (Dec 2015); planephd PAPI estimate ~$343k for a 1984 model (Mar 2026); aeromercado.com.br BR asking $1.1M (1983, now sold); Controller search-snippet asking range $1.295M-$2.75M (mostly Diamond I/IA, optimistic/outliers). Realistic transaction value clusters ~$250k-$350k wholesale/retail; max anchored to documented real BR asking ($1.1M). Sits at extreme bottom of 'light' band as expected for a 40-yr-old orphaned type. Operating cost from aircraftcostcalculator Diamond 1A (variable ~$2,247/hr; ~$3,515/hr all-in at 450 hrs, $6/gal); fuel burn ~206 gph / ~1,200 lb/hr (planephd, AOPA). Charter proxied via identical Beechjet 400 airframe.

AOPA - Quick Look: Mitsubishi Diamond IA, fetched; VRef $225k (1982) to $300k (1985); fuel ~1,200 lb/hr; 2,500 lbst JT15D-4D; cruise 420 kt
