Dear Kittiya,
Consultant Contract 13/662 (Thai Airways B787) had been issued too early in order to renew contract 12/597 (Thai Airways B787) in case of
B787 MBD Sales Contract not signed by Thai before December 31st 2013 (Term of contract).
In final, B787 MBD Sales Contract has been signed by Thai Airways on December 27th 2013, so consultant contract 13/662 has been consequently deleted.
To cover Thai B787 activities, the consultant contract 12/597 issue 1 (+ its amendment N° 1) remains the only one under validity.
Amendment N° 1 concerns your Bank Account modification, no need to renew it. December 31st 2014 was the limit date for signing by Skytech.
The term of remuneration (Aircraft Fee) to Skytech under Consultant Contract 12/597 Issue 1 is managed by the article 7.2.3. of such contract.
That means until December 26th 2018 or at delivery of the 8th Aircraft B787 equipped MBD to Thai whichever comes first.
