__________________________
1) Year of construction is coded by the third capital letter of the serial number on the type plate:
S = 2002, T = 2003, U = 2004, W = 2005, X = 2006, Y = 2007, Z = 2008, A = 2009, B = 2010, C = 2011, D = 2012, etc.
Example: Serial number ARSH-0054, the 3rd capital letter is S, so the year of construction is 2002.
