Tirvengadum remained MD of the national airline corporation until February 1997 when he was succeeded by Nash Mallam Hassam.^[7]

After leaving Air Mauritius, Tirvengadum became Chairman of airline company Air Afrique which is based in Ivory Coast.^[8] He led that organisation until 30 January 1999 where he was succeeded by Tijane Sylla.^[9]

In 2001, the illegal practices involved in the Caisse Noire Affair came to light^[12] and, on 22 February 2002, Tirvengadum and other officials of the national airline company and Rogers Limited were arrested and prosecuted. Whistleblower Gérard Tyack, who was General Manager of Air Mauritius, revealed the existence of a Swiss bank account in Geneva for the payment to officials of Air Mauritius, journalists and politicians, as well as to finance political newspapers, electoral campaigns, purchase of private cars for Sir Harry's wife and their daughters' overseas studies. The illicit bank account had been set up following Sir Seewoosagur Ramgoolam's request for funds in 1981 to assist Advance which was the ailing propaganda newspaper of the Labour Party.^[13]

Gérard Tyack spent 2 years in jail, Robert Rivalland of Rogers Limited was acquitted in 2015,^[14] whereas the prosecution against Tirvengadum was placed on hold due to his purported ill health.^[15]
