London, England (CNN) -- Shares in Rolls-Royce rose Monday after the company announced that it had made progress in understanding the cause of a Qantas mid-air engine blow-out. The shares rose by 2.62 percent -- they had been 14 percent down from Thursday after the Australian carrier revealed early Monday that oil leaks had been discovered in the engines on three of its planes after being examined by Rolls-Royce engineers. This follows last week's aborted flight by an A380, which was forced to make an emergency landing in Singapore shortly after take off when one of its engines failed. Rolls-Royce on Monday issued a statement saying the Qantas problem was caused by an "incident specific to the Trent 900 engine."
