SofemaOnline reviews the errors specifically attributable to interaction with documentation in the production of task cards and other maintenance data.


It is both understood and recognized that certain aircraft maintenance errors are strongly linked to the issue of documentation both related to its content as well as the lack of use/engagement.

Related to technical authorship the primary concern is that the technician may misunderstand the information/context and as a result use their own knowledge instead of seeking clarification of a potential anomaly.

SofemaOnline takes a look at the pros and cons of aircraft lease options

The acquisition cost of aircraft is a significant undertaking with Boeing & Airbus Narrow Body Jets around the million USD.

Serious discounts are on offer for multiple purchases and with the buying power of the large leasing companies typically able to order aircraft well into double digits the leasing companies are able to generate interesting options for operators whereby the cost of acquisition can be more competitive from a leasing company than going to the manufacturer directly.

Note - Whilst this applies of course to new aircraft and the leasing companies have the added advantage of a portfolio of pre-owned aircraft.
