Analysis

The scheduled flt depd bethel, AK, with a wx dispatch release. When the flt reached the destn (Chevak, AK), the station manager (a non-certified wx observer) adzd the flt crew to not attempt a lndg, because the wx was not good. According to the flt crew, however, the fog was not obscuring the rwy & they elected to make an apch. According to the pilot (PIC), a high sink rated developed on short final & he did not apply power. He believed the lndg flare would have arrest the sink rate. However, the acft lndd hard on the rgt main gear, causing it to sep & dmg the rgt main wing strut. The rgt wing settled to the surface & the acft yawed to the rgt, veered off the rwy & was further dmgd. The load manifest did not comply with 14 CFR part 135.63(c) or the company's operations manual.
