707 Made “Economically Obsolete”?:

A Federal Aviation Administration directive, patterned after a Boeing recommendation for structural modifications, threatens to make the 707/720 “economically obsolete”, according to Av Week.

The directive comes as a result of a Boeing recommendation prompted by fatigue cracking and corrosion detected in the aircraft. The FAA notes that some 43 US registered 707/720s and up to 400 foreign aircraft could be affected by the directive. Kits for upgrading the aircraft cost $US380,000, with associated costs taking the upgrades closer to the $US1m mark. This, it is claimed, will make it economically unviable to update the older generation aircraft, particularly in a time of declining used aircraft prices.
