In our judgement, the wings of the Arrow Air DC-8 were not contaminated by ice - certainly not enough for ice contamination to be a factor in this accident. The aircraft's trajectory and performance differed markedly from that which could plausibly result from ice contamination. The aircraft did not stall. Accordingly, we cannot agree - indeed, we categorically disagree - with the majority findings.

The available evidence convincingly shows that the right outboard engine was producing little power before it contacted trees. The investigation of the other engines was inconclusive with regard to pre-impact status. We believe it possible that these engines were also operating at reduced power. All four thrust reversers may have been deployed.

The evidence shows that the Arrow Air DC-8 suffered an on-board fire and a massive loss of power before it crashed. But, we could not establish a direct link between the fire and the loss of power. The line may have been associated with an in-flight detonation from an explosive or incendiary device. Consequential damage to various systems precipitated the crash.
